Visit Site

Constant Contact is our pick as the best overall email marketing service – it has everything a small business needs to create effective campaigns, with affordable plans and easy-to-use tools. You can send an unlimited number of emails, and prices are based on the number of subscribers on your contact list. Its email editor is very simple to use, and when we sent emails with Constant Contact, they went to the right inboxes.

July 2021: Constant Contact recently announced it has acquired SharpSpring, a cloud-based revenue growth and marketing automation platform that is designed to help boost the effectiveness of the marketing strategies of small businesses. Constant Contact users will now have access to the SharpSpring platform to help further their engagement with customers throughout their buying journey. 

April 2021: Constant Contact and Vimeo recently announced a new strategic partnership to provide email marketers with the ability to create, host and manage video within the Constant Contact platform. Users can create videos, embed GIFs, capture and sync leads, and measure video performance on any given campaign.

Constant Contact Pricing

Constant Contact has two plans, Email and Email Plus, that can fit into the budgets of most small businesses. Additionally, Constant Contact offers a 60-day free trial.  

Both plans have everything you need to create professional email campaigns. With each plan, you can send unlimited emails. Each plan comes with customizable templates, contact management and list-building tools, pop-up forms, tracking and reporting features, an image library and a mobile app.

The difference between the two plans is that Email Plus offers dynamic signup forms, 2GB of file storage, access for up to 10 users, email automation, event marketing, online donations, plus surveys and coupons. Here's more that you should know about Constant Contact's pricing:

  • The prices for both plans are based on list size. If you prepay for six months, you receive a 10% discount; if you prepay for 12 months, you get a 15% discount. Additional discounts are available for nonprofits. Special plans are available for franchises and associations.

  • Prices for the Email plan start at $20 per month for up to 500 subscribers and $65 per month for up to 5,000 contacts. The most expensive package is $335, which supports 50,000 contacts.

  • The cheapest package for the Email Plus plan starts at $45 per month, and you can send emails up to 500 contacts. For 2,500 contacts, the cost is $70 per month. The most expensive package is $335 for 50,000 contacts.

  • If you have more than 50,000 subscribers, you need to reach out to Constant Contact for a price quote.

  • If your contact list changes from one billing cycle to the next, Constant Contact will automatically adjust your fee.

  • The 60-day free trial includes all of Constant Contact's tools, including templates, images, an email editor, contact management, reporting and live support. But, you can only send emails to 100 contacts or less.

Constant Contact Features

Constant Contact has an array of tools that make it easy to create eye-catching, appealing email marketing campaigns. Here's what we liked about Constant Contact.

A/B Split Testing

With Constant Contact's A/B testing feature, you create two different subject lines that are each sent to a portion of your contact list. The software determines the better-performing subject line and automatically sends the winner to the rest of your audience.


With Constant Contact's autoresponders, you can create a series of personalized, automated emails that will be sent automatically based on certain triggers. You can automate emails such as welcome messages to new subscribers, and birthday and anniversary emails to existing customers.


Constant Contact boasts a 97% deliverability rate. The company also offers resources on its website where you can learn about email best practices and phrases that may trigger spam filters.

Email Editor

When you click "Create Email," you have the choice to add your website. If you select that option, Constant Contact scrubs your website to find your brand's colors, logo and social media accounts, then adding them to the email. Next, you pick a template and edit it using the drag-and-drop tools. If you aren't sure how to use the email editor, a video automatically plays when you're in the editor for the first time. When we used Constant Contact's email editor, we created and sent an email in less than 10 minutes. The emails we sent hit the right inboxes, not the "spam" or "promotions" folder.

Email Templates

Constant Contact has dozens of templates in its library. Each template is reusable and built for both desktop and mobile. Once you pick a template, you can customize it with your own images as well as your brand's colors and fonts.

List Management

You can upload your existing contacts with Excel, Outlook and Salesforce. When you upload new contacts, you can use tags to categorize them, such as "VIP donor" and "prospect." Constant Contact automatically removes duplicates and unsubscribed contacts for you so you don't have to manually manage your lists.


Once you send emails out, you can immediately view reports from the campaign. Statistics include open rates, click rates, the number of emails sent, bounces, successful deliveries, unsubscribes, spam reports, and did not opens. You can also view what links are clicked, social media statistics and poll responses. In this dashboard, you have the option to resend an email.


We found a lot of positives to Constant Contract. Among the benefits that stood out most to us include: 

  • Ease of use: Constant Contact is one of the easiest email marketing services to use. Its email editor is outstanding. Even if you have never designed an email, the editor automatically scrubs your website to find your logo, colors and social media profiles. Once it has this information, you can easily customize templates to create an appealing email. There are dozens of templates to pick from, and you can save your favorite templates so you can quickly reuse it to create a new email. 
  • Integrations: Constant Contact integrates with several other services, such as Excel, Salesforce, Outlook and list-building tools. You can sync contact data easily and so much more. Constant Contact has integrations for the software applications that a lot of small businesses use and rely on. 
  • Automation: You can send automatic emails triggered by customer actions so you have a response in place when consumers are interested in your products or services.


There were a couple of potential drawbacks to be aware of. Here are some limitations of Constant Contact.

  • No free option: While Constant Contact has a 60-day free trial, many email marketing services provide a free version of their software, often with limited capabilities. Constant Contact does not offer a free option.

  • Limited A/B testing variables: The best email marketing services let you compare multiple variables with your A/B tests, such as different designs. Constant Contact's A/B testing feature only lets you change email subject lines, which is limiting.

Customer Support

Constant Contact has a variety of resources to help you. Along with its extensive knowledgebase and videos, it offers chat and phone support. When we reached out, Constant Contact's representative was helpful and not at all pushy, and answered all of our questions.


Benchmark Email: Best Low Cost Email Marketing Service

Benchmark offers a mobile app for on-the-go access.
The software includes a responsive email creator.
Emails may land in spam folders if you use a personal address.

When looking for an email marketing service, it's important to find one that offers all the tools and features you need at a price point that makes sense for your business. Benchmark is our best pick for a low-cost email marketing service because it has a wide range of plans to suit the budget of any small business. Benchmark also boasts key automation features to make your email campaigns more efficient and effective, as well as responsive templates and an easy-to-use email editor.


Benchmark Pricing

A standout benefit of Benchmark is the selection of service plans it offers. The plans are based on the number of subscribers your business has. All plans include a simple drag-and-drop email editor, responsive templates, signup forms, basic drip campaigns, RSS email campaigns, email delivery management, Google Analytics tracking, list management and segmentation, list hygiene, reports, surveys and polls, unlimited video storage, and 10MB of free image gallery storage. All plans also offer multiple integrations, including ones with social media, e-commerce, email templates and existing contact lists.

Here is a breakdown of Benchmark's pricing and terms:

  • With its free starter plan, you can send email campaigns to an unlimited number of subscribers and up to 250 emails per month. This free version includes a lot of services, but it's missing some key features, such as behavior-based email follow-up and list management automation, website engagement automation, automated customer journey templates, automated responses to shopping cart abandonment, targeted emailing, master accounts and subaccounts, and A/B testing. You can start with the free plan and upgrade anytime you want.

  • Paid packages start at $13.99 per month for 600 subscribers. Every paid plan includes every feature, including Benchmark's automation tool (Marketing Automation Pro) and unlimited email sends.

  • If you have 1,000 subscribers, the packages start at $21.99 per month. Prices start at $31.99 for 2,500 subscribers, and at $81.99 for 10,000 subscribers.

  • Benchmark has plans for every size of business, including those with massive contact lists. Its most expensive plan is $29,200 per month for 7.14 million subscribers.

Add-ons are available with any plan. For instance, the list verification add-on ensures you have the highest-quality subscribers and deliverability. This feature is an extra $3 per month for every 1,000 subscribers.

For an extra $5 a month, you can upgrade from basic storage to unlimited storage for image hosting. You also have the option, for $28.95 per month, to add a dedicated IP, which gives you more control of your sending reputation and delivery to inboxes.

To see how your email campaigns will look on any device on every browser, you can add inbox checkers for an extra $14 per month for 100 tests. Benchmark doesn't offer a free trial, but you can try out its free version before upgrading to a paid account.

Benchmark Features

Benchmark has a vast set of features and tools that anyone can use to create successful and attractive email campaigns.

A/B Split Testing 

You can compare campaigns to determine which one performs the best. For instance, you can test two different subject lines and send the highest performer to the remaining subscribers. A/B testing is also available for delivery times; Benchmark will determine when your subscribers are most likely to open your email campaigns.

Email and Newsletter Templates 

Benchmark has an extensive list of attractive and customizable templates for different industries, holidays and email types. Once you pick a template, it's simple to customize it with your brand's colors, photos and logo.

Email Designer 

Benchmark offers different features that make it simple for any marketer to create an eye-catching email. The drag-and-drop editor allows you to create emails from a layout or template, so you can deliver a professional and attractive newsletter even if you lack graphic design experience. All you have to do is drag and drop feature blocks and images into place.

The tools to create automatic responses, surveys and polls are also very user-friendly. Each takes you through the process step by step. You can edit your images by adding effects, stickers or a message over your photo. Even if you're new to mass-email software, you can easily create successful email campaigns.

The code editor is for individuals who want to do their own coding. You can write your own HTML or copy and paste from another source. With the plain text editor, you also have the option to create text-only emails with no images or formatting options. If you're good at HTML, you can build your own email from scratch or edit the HTML of a template. You can use the dual view to see the design of the email while you're still editing it.  

Inbox Checker 

Before you send out your email, you can preview it in Firefox, Internet Explorer and Chrome. Along with web-based previews and Window and Mac OS inboxes, you can see how it will appear on mobile devices.


Benchmark works with more than 300 other applications, including WordPress, Facebook, Google, Shopify, Slack, Etsy and Salesforce. With the WordPress plugin, you can build an email list directly on your WordPress website and send email versions of your blog posts. With Facebook, you can put Benchmark's email signup form on your business's page to allow visitors to subscribe to your emails without leaving Facebook.  

List Builder 

Along with attractive emails and effective drip campaigns, building your list of contacts is critical to successful email campaigns. To get users to subscribe, you can put Benchmark's popup and embeddable email signup forms on your website, blog or social networks.

The list management tool allows you to segment, import and integrate your contact lists. You can segment your lists by demographics, likes and dislikes, or geolocation to send the most appropriate content to each customer.

You can add contacts to your list one at a time by copying and pasting in email addresses, or in bulk by importing XLS, CSV and TXT files. Benchmark integrates with a lot of third-party applications, which makes it easy to upload your existing lists from other services. When you input contacts, you can also enter a lot of information about each one – including their address, phone number and important dates like their birthday – to build comprehensive customer profiles. This information is particularly handy for drip campaigns.

With contact list automation, you can automatically send emails based on each contact's information, like a birthday discount or other event-based email. You can also automate actions based on customers' opens and clicks in email campaigns.

Marketing Automation Pro 

Benchmark's Marketing Automation Pro gives you the ability to send out automated email series triggered by website and email engagement. With this tool, you can easily design a customer journey and not worry about sending follow-up emails.

Marketing Automation Pro works by allowing you to pick a trigger, such as when a customer subscribes and is added to your contact list. Then Benchmark sends the email you chose – in this case, a welcome email. It will then follow up at the optimal time, usually a couple days later.

Benchmark allows you to create multiple automated journeys for your customers. You can use one of its marketing automation templates or create your own. Its featured templates include welcome messages for new subscribers, promotions that target follow-ups based on opens or clicks, and feedback requests.  

Email Campaign Analytics 

Once you send your email, you can immediately view a report that shows the total numbers of recipients, opens, clicks, bounces and unsubscribes. The report graphs the data in a way that's easy to understand. This dashboard shows your campaign's link performance, displaying the URLs clicked and a click map. You can also view opens by geolocation of customers.


As one of our best picks, Benchmark offers considerable benefits. These are some we found especially valuable.

  • Ease of use: Of the email marketing software tools we reviewed, Benchmark is one of the easiest to use. All of its tools walk you through each step. If you're unsure how to use any of the tools, there are support options to help you along the way, such as live chat, a blog, a monthly newsletter and videos describing how to use each feature. It also has a phone line and email available for customer service.

  • Responsive email creator: When we used Benchmark's drag-and-drop editor, we were able to create an interactive and responsive email with custom pictures, colors and content in a matter of minutes. With more than 200 templates designed for specific industries and holidays, it's easy to find a relevant template. Another tool that makes building emails a breeze is the image library. You can add frequently used pictures, such as logos in your library, in seconds.

  • Contact management tool: Benchmark's contact management and automation tools are simple to use. Each tool provides easy-to-follow steps, and there are videos throughout the dashboard to ensure you know what you're doing.   

  • Mobile app: Benchmark has a mobile application for iPhone and Android that makes it easy to view your emails, add contacts and see analytics on your email campaigns.

  • Variety of plans: Benchmark offers a selection of plans based on the number of subscribers a business has, and it has a free version you can test before committing to a paid service.


The only problem we had with Benchmark was that our emails sometimes landed in spam folders. However, we sent emails from a personal Gmail account, which are less credible than emails sent from a company or business domain. When you select a personal email as the "from" address, Benchmark warns you that using a personal or general ISP email address like Gmail, Yahoo, or Outlook hurts delivery rates.

Customer Support

We were pleased with Benchmark's customer support. The representatives were prompt and courteous when we spoke over live chat, answering all our questions. You can contact Benchmark by phone, live chat or email.


Mailchimp: Best Free Email Marketing Software

Users of Mailchimp have access to a full-featured free version.
The Mailchimp interface is very user-friendly.
Mailchimp does not offer live chat support with its free plan.

Mailchimp is our pick for the best free email marketing service. When you're looking for an email marketing service, it's important to find one with a range of tools that make creating successful, professional email marketing campaigns simple and easy. You want a service that has an easy-to-use email editor, with the capability to create segmented lists and drip campaigns, which are prewritten messages sent to customers in a series of emails. Other key features to look for include contact management tools, detailed reports and analytics, A/B split-testing tools, spam filters that ensure your email lands in customer inboxes, and automated workflows. The best email marketing services offer a free plan or at least a free trial so you can test out the platform before spending valuable marketing dollars. Mailchimp checks all of these boxes.

May 2021: Mailchimp recently unveiled two new commerce features for free on their all-in-one marketing platform: Stores and Appointments. Stores allows business owners to create online storefronts in which they can add and edit products; process orders; and configure payments, taxes, and shipping. Appointments will enable businesses to manage schedules and offer service bookings online.

February 2021: Mailchimp has acquired text message marketing company Chatitive. Initial reports suggest the two services will continue to operate independently in the short term. Mailchimp CEO Ben Chestnut suggested that the SMS capabilities of Chatitive will soon be integrated into Mailchimp's platform. This would allow small businesses using Mailchimp to run SMS marketing campaigns from the same platform they conduct email marketing campaigns.

December 2020: Mailchimp has partnered with Fastbase to launch LeadScoring for Mailchimp. The partnership gives Mailchimp users access Fastbase's lead-scoring tool. Lead scoring "rates" the likelihood of prospects to buy your goods or services. With lead scoring, Mailchimp users can run highly targeted  campaigns, directing emails to the most pertinent audiences with highly appealing content designed to convert them from a lead to a customer. According to Fastbase, users  get the first 100 leads for free. After that, LeadScoring is available as a monthly subscription.

Mailchimp Pricing

Mailchimp offers multiple plans that can fit into the budget of nearly any business. Each plan includes multiuser accounts, Mailchimp's extensive knowledgebase, marketing automation, target and segmented lists, as well as analysis and testing features. Besides creating and sending email campaigns, users can create landing pages, pop-up forms, Google Remarketing Ads, and Facebook and Instagram ads with any plan. 

Here is a breakdown of Mailchimp's plans and what they offer: 

  • Mailchimp's Forever Free plan comes with an extensive list of features. Free plans accommodate up to 2,000 contacts, and you can send up to 12,000 emails per month. This plan is free until you have more than 2,000 contacts. 

  • The Essentials plan is based on the number of subscribers you have. Prices start at $9.99 per month for 500 contacts and end at $25 per month if you have between 1,501 to 2,000 contacts. The Essentials plan includes everything in the free plan along with the ability to add custom branding, access to live chat and email support, more target and segmentation tools, as well as increased reporting and testing tools. To find out how much you would pay for the Growing Business package, use Mailchimp's pricing calculator. 

  • Mailchimp's Standard plan starts at $14.99 per month for 500 contacts and includes everything from the Essentials and Free plans, plus advanced analytics, retargeting ads, custom templates, and event-based automation series.

  • Mailchimp Premium starts at $299 per month; it is suited for larger businesses that require increased capabilities and support. Premium includes all the features from the previous plans, plus advanced segmentation, multivariate testing, unlimited role-based user access and phone support.

Mailchimp Features

Here are some of Mailchimp's best features.

A/B Testing

With A/B testing, you can determine what subject lines are the most effective, what name should be in your "From" field, and if different times affect the click rate. Mailchimp's A/B testing lets you determine the size of your sample group and build three different versions. It sends the winning email to the remainder of your contact list. 


Even with the Forever Free plan, you get a good set of metrics. The Reports dashboard informs you who opened your email, what links they clicked, what emails bounced and who unsubscribed. The reports also document successful deliveries, the number of forwards, clicks per unique opens and spam complaints. Mailchimp tracks subscribers with the most opens and the social performance of your campaigns; the numbers and reports are outlined in graphs, which makes understanding the data simple. 


With Mailchimp's marketing automation tools, your emails get to the right people at the right time. You can target campaigns to contacts based on behaviors and preferences. When you create automated campaigns, you can pick from pre-designed workflows or build your own with custom rules. Mailchimp's automations include a welcome series, a happy birthday email and notifications for new blog updates. Others are available based on subscriber activity, e-commerce workflows and more. 

Build Ads and Landing Pages

With Mailchimp, you can create Google, Facebook or Instagram ads. You can also create mobile-friendly landing pages. Mailchimp has two versatile landing page templates that you then modify to create and publish landing pages. 

Email Editor

Mailchimp's email editor is simple. To get started, you can begin with a basic layout, themed template or code your own email. Its responsive templates and designs are created for all devices, including desktop and mobile. With the email editor, you can personalize the "To" field with each contact's first name, last name, or both. You then set how the sender will be listed and what the subject line will be with your email. When it comes to the design of your email, drag-and-drop tools make it simple to customize every aspect of the template: text, dividers, images, videos, social shares and social follows. You can also add frequently used pictures, such as logos, to your image gallery so it's easy to quickly find and insert pictures. Before sending your email, Mailchimp scans it for any errors that could cause it to land in a spam folder. You also have the option to share your campaign on both Facebook and Twitter.


Mailchimp integrates with several applications, including hundreds of e-commerce apps like Shopify, Magento, WooCommerce, PrestaShop and BigCommerce. By integrating Mailchimp with your e-commerce store, you can capture order information, create targeted campaigns, automate follow-ups and send personalized notifications. 

Mailchimp Pro 

Mailchimp Pro is an add-on with advanced features. It costs $199 per month (sorry, Pro cannot be used with the Forever Free plan) and for that monthly fee, you get more list segmentation options, additional list fields and TimeWarp. With the regular Mailchimp, you are allowed 30 list fields; Pro users, however, have access to 50 more fields. These extra fields let you personalize and target your campaign content. TimeWarp schedules delivery of email campaigns based on subscribers' time zone. Another thing that's unique about Mailchimp Pro versus the other plans is greater flexibility with A/B split testing. For instance, you can preview your email and see exactly what it will look like in different email clients and on different devices. While regular Mailchimp plans come with A/B testing, the Pro add-on includes a more robust version that lets you test multiple variables to see how various changes affect different aspects of your campaigns. Finally, Mailchimp Pro provides better analytics, including comparative reports, compliance insights, delivery insights and stop delivery.


There are a number of benefits to using Mailchimp, including:

  • Ease of use: Even if you've never used an email marketing platform before, rest assured, Mailchimp is extremely easy to learn and use. The dashboard is easy to understand, and it's simple to find the features and tools you need. Its email creator offers step-by-step directions, so it's hard to miss a step. Mailchimp also offers drag-and-drop tools that make creating emails, adding pictures, and customizing emails simple.

  • An online knowledgebase: If you have a question, you can browse through Mailchimp's knowledgebase and blog that offer answers to a number of frequently asked questions. It has guides on how to build an email list and how to create a marketing automation journey.

  • A mobile app: Mailchimp's mobile app lets you create and send campaigns from your phone or tablet. You can also manage lists, add new subscribers and analyze reports on the go. Additionally, the app can send you sales notifications and daily summaries of your campaigns' performance.

  • Automation: With Mailchimp's free version, there are more than enough analytics to pinpoint what is working with your email campaigns and what isn't. The reports show who is opening your emails, what links people are clicking on, who unsubscribed, and what email addresses bounced. 


There are a couple of items to be aware of with Mailchimp. Here's what you need to know before signing up:

  • Limitations with the free plan: The Forever Free plan doesn't provide ongoing customer service. You get access to email support for 30 days, and live chat isn't offered at all. However, there is an extensive knowledgebase and blog that can answer most of your questions.

  • Deliverability with Gmail: A second concern with Mailchimp concerns how emails are delivered in Gmail. Mailchimp states that it doesn't have any control when it comes to the placement of its emails in Gmail. When we sent emails to Gmail accounts, they landed in the promotions tab. While the promotions tab is better than having your email go to the spam folder, users are less likely to check that tab as often as the primary tab in Gmail.

Customer Service

Mailchimp offers online resources and a contact form available on its website. And while live chat isn't available with free accounts, when we reached out to Mailchimp through email, we received a response the next day. The representative answered all our questions and wasn't pushy. When you sign up with the free plan, you have access to email support for the first 30 days. After that, if you need one-on-one help, you can always browse through Mailchimp's guides and tutorials. And if you decide you want more features with your emails, Mailchimp's paid plans are very reasonable and still easy to use.

Sendinblue offers several advantages that made it one of our best picks. These are some aspects that make it particularly useful.

  • Free plan: Rather than a free trial, Sendinblue offers a free version of its software that allows up to 300 emails per day and unlimited contacts, with no contract or credit card details required. The free version provides all the necessary features to create an effective email campaign, and you can use it for as long as you like.

  • Ease of use: Sendinblue's email creation tool is straightforward and easy to use, with a drag-and-drop editor and a selection of email templates. You can upload your own images, though they must be 5MB or smaller, and edit them with a variety of built-in tools.

  • SMS capability: Sendinblue also offers SMS (texting) integration, meaning you can import your texting contacts and send text-message campaigns with your email marketing account.

  • Marketing automation: Sendinblue offers several marketing automation features – including detailed workflows, custom rules and triggered emails – to save time and streamline your campaigns.


Despite its many benefits, there are a few potential issues that large businesses should be aware of before moving forward with Sendinblue. 

  • Basic templates: The predesigned templates are limited compared to some other companies' selections, and you cannot customize them – which would be fine for a company looking for simple and straightforward templates, but not ideal for a large company with complex, highly specific needs and widely diverse audience segments.

  • Limited integrations: Sendinblue does offer a variety of integrations with other programs, but it has fewer than most of the other companies we reviewed, so it may be missing an integration with software that's an important part of your workflow.

  • Low daily send limit on free plan: While the free plan offers many features, it has a daily send limit of 300 emails. While this is pretty standard for a free plan, large businesses should consider this before opting for the free version. For many midsize and large businesses, this may remove the otherwise-convenient free plan as an option..

Customer Support

Sendinblue offers multiple help pages, online tutorials and FAQs, and an online submission form and phone number for technical help. When we reached out to the company, we spoke to a friendly and helpful representative who answered our questions and was not pushy in trying to sell us on the software.

January 2021: Sendinblue has launched a free email marketing certification course designed to help professionals increase and strengthen their email skills. The course addresses topics such as email deliverability, A/B testing, segmentation, optimization, subscriber list growth and GDPR compliance. Upon completion of the course, participants receive a personal expert certificate.


How Much Will You Spend on an Email Marketing Service?

Most email marketing providers charge a monthly fee based on the number of contacts you have and the number of emails you plan to send. Plans then vary further based on specific features. 

On average, monthly plans range in price from $10 per month for 500 contacts to $4,000 per month for 1 million contacts. Services that have a free option typically provide limited features in the free version and cap the number of emails to 10,000 per month. 

For businesses that only occasionally need an email marketing service, some providers allow per-email or pay-as-you-go pricing. This is a flexible option ‒ you only pay for what you use rather than paying money each month for a subscription that may go to waste. 

Most email marketing services offer a free version of their software or a free 14- or 30-day trial so you can test out the software and see how it works for you. 

We recommend trying as many free trials as you can during your search so you truly get a feel for which email marketing service offers the best solution for your business. Pay attention to how easy it is to design emails, seek out services that offer the marketing automation features you want (e.g. autoresponders, templates, etc.), and see what other applications the software can integrate with.

Buying Guide

Negotiation Tips

Most email marketing plans' pricing terms are set in stone, but there is one way to get a discount: If you prepay for a year upfront, you typically receive about 15% off. Most services also offer discounts for qualifying nonprofits.

Email Marketing Services Features

As you compare email marketing services, here are some core features you want to look for.

  • An email creation tool: Most services provide a user-friendly drag-and-drop tool that allows you to customize your emails, or customizable pre-made templates. Some providers have templates that show you how your email will look on multiple devices, including laptops, tablets and mobile phones. This can help you design a flexible and responsive email. An easy-to-use and responsive email creator is critical. The best email marketing tools also have extensive templates that work on both desktop and mobile devices.

  • Analytics: Once you send an email, you'll want to determine how it's doing. Most services provide a range of data, including how many emails you sent, how many of them landed in inboxes, the bounce rate, who opened your emails, and the number of clicks and opens by location. Click-through and open rates are two basic metrics all email marketing services should provide. Those are important metrics to track for businesses.

  • Marketing automation tools: Marketing automation is the ability to send specific, targeted emails to certain customers when they complete a certain action. For example, if a visitor to your website signs up to receive emails from you, your email marketing provider's marketing automation tool will trigger a welcome email to be sent to that customer's inbox. Marketing automation can be an effective timesaver, and many email marketing services are creating ways to make automated emails more personal, which leads to higher engagement and ROI.

  • Segmentation: This is another helpful way to deliver more relevant messages to your audience by grouping them by things like age, location, gender, industry or interests. Segmentation allows you to send different emails to different groups, rather than sending one mass email that may not be relevant to your entire customer base. Segmentation tools let separate contacts into specific groups to ensure they only receive content that's relevant to them. Creating smaller email lists within your one large email list helps you target groups more effectively.

  • Contact management: Your subscribers are the key to successful email marketing campaigns, so it's important to manage those subscribers efficiently. If your list has duplicate contacts or contacts who have unsubscribed, it hurts you. A contact management tool will help you acquire, sort, and manage your email contacts; it should provide features like automatic deletion of dead or duplicate contacts, importing, exporting, grouping, and integration with other management tools like a CRM or CMS.

  • A/B split testing tools: These tools let you test different variables in your email and then the software selects the better-performing version campaign. While most email marketing services offer this for subject lines, the best programs can test success rates based on multiple variables in your emails.

  • Inbox previews: You can see how your email will look on different devices and desktops before you send them.

  • Spam filters: It's vital that your emails go to the right place; they aren't doing any good in a spam folder. Thankfully, the best email marketing services have tools in place to ensure your customers see them.

  • Social media integration: Most email marketing services will integrate with social media platforms, which allows you to grow your contact list, schedule posts and track your followers' engagement to determine what's popular. Integrating your social media with email marketing will help you make the most of multichannel marketing by providing you with more information about your customers as well as more opportunities for them to see messages from you.

How Will My Business Benefit From Email Marketing?

As a small business, your marketing dollars matter. They have to deliver strong results, but you also can't afford to spend thousands on software when you have bills and employees to pay. Email marketing is an effective, low-cost method of communicating with your customers and building loyalty to your company. Email marketing delivers other benefits as well.

You can easily manage email campaigns.

First and foremost, an email marketing service provides you with one centralized place to create, manage and analyze your email campaigns. The software manages the entire process of creating and sending your email campaigns. It also gives you feedback on how your campaigns are performing.

Email marketing can improve your click-through rates.

A professional-looking email campaign will entice customers to click on the links you include in the email, which means higher click-through rates.  In the end, that results in increased traffic to your website.

You can provide personalized communication to consumers.

Customers in 2020 are expecting to see content that is personally tailored to them, rather than a rote mass email going out to a company's entire customer base. Email marketing services allow you to segment your customers by qualifiers such as age, gender, location and interests to help you customize your messages.

It offers multichannel marketing.

Many email marketing services allow you to embed or link to your social media platforms in your emails, which creates the opportunity for your business to advertise through multiple channels. This helps to increase brand awareness and the likelihood of return customers.


Q: What is an email marketing service?

A: Email marketing is a digital marketing strategy where you send emails to customers and prospective customers. When email marketing is leveraged effectively, it can turn a one-time customer into a loyal customer. Email marketing services help you create eye-catching, professional emails, but it doesn't end there. Many services let you create automated responses, such as an email series welcoming a new subscriber who has signed up for your email list or offering a discount on a customer's birthday. This automation is helpful for small businesses – it allows owners to focus on running their business while their marketing strategy runs in the background; small businesses can continually gain new customers and grow. Finally, many services integrate with contact management so your contact data is always synced and up to date. 

Q: Why should I use an email marketing service?

A: While email marketing isn't necessary for every business, it is a good way to reach customers and improve your overall marketing strategy. Email is one of the world's most-used communication channels, which makes it a prime opportunity for businesses to get their message out. Email also has an ROI of 4,400%, according to the Data and Marketing Association, which is three times higher than social media. 

Q: How can I make my email marketing stand out?

A: With so many businesses using email marketing, it's important that your campaigns are relevant to your customers and subscribers. Selecting the email service that best fits your business is the first step in helping your campaigns stand out. After that, you'll want to use tools like list segmentation and automated responses to best cater to the wants and needs of your customer base. 

Q: What are the most important elements of email marketing?

A: Your business should aim to provide a balanced mix of promotional content and organic content. Much like a social media marketing strategy, you need to add value to the inbox or feed of your subscribers. If a customer subscribes to your emails, send them emails that relate to them. This is where segmentation becomes valuable. Writing in a tone that matches your business's brand is also a best practice. If you stick to your brand identity and send emails that add value to your subscribers, you'll be in good shape. 

Q: How can I decide which email marketing service is best for my business?

A: Businesses have different needs, and email marketing services have different strengths. If you're running basic email marketing campaigns, the least-expensive services probably make the most sense. If you're a bigger company sending emails to thousands of people, you need an email service that can easily handle that number of contacts while ensuring maximum deliverability with few errors. 

The most important factor driving your decision will be the number of emails you plan to send each month and how many subscribers you plan to have. This will give you a ballpark price point. Once you know the number of emails and contacts, then you need to determine which features you must have, which ones you'd like to have but are nonessential, and which features you do not need or want. Start with our best picks above, then read our review of the service or services that appeal to you most – we have listed the plans each service provides, the number of emails and contacts each plan supports and the features that come with the service. Be sure to read our pros and cons, too, so you get a sense of whether the software will meet your needs. 

When looking for the best email marketing service for your company, what are your needs? Are you looking to send email newsletters or are you looking to send mostly promotional emails? What metrics are the most important for your business to track? Some business value click-through rates, others value other metrics like the open rate of your emails. 

You may also want to look at features like opt-in forms, which help you legally obtain the email addresses of subscribers. 

Finally, choose a service that offers has a clean and intuitive interface so it's easy to find the tools you need. You'll also want the service to have an easy-to-use email editor, contact management tools, and drag-and-drop automation tools.

State of the Industry

Email marketing is in a good place in 2020. Businesses use it frequently as part of their overall marketing strategy and companies are getting $44 per every dollar spent on email marketing, according to a recent report from Campaign Monitor. Email marketing is a popular marketing channel.

Automation is an emerging trend in the email marketing space. The ability to send pre-written emails to customers once they trigger a cue is a great marketing tool. For example, a clothing store might send a special discount coupon to a customer on their birthday. This email can be identical for each customer, aside from their name, and the email can be scheduled to send every time someone's birthday comes. Marketing automation allows you to reach customers without having to put together a unique email every time an event occurs. Depending on the size of your business, automated emails can save tremendous amounts of time.

Monitoring the popularity and usefulness of email tools is important. As the industry changes and different trends emerge, you want to stay on top of what your customers want. If you run an extremely small business with a subscriber list of 200 people, automation might not be for you. You might benefit more from very personal email campaigns that engage those people, while larger businesses with thousands of subscribers might see better results from automated emails. As the industry changes, it's important to understand how your business works and that some tools might not make sense for your business. Don't jump on every email marketing trend.

The email marketing industry also has a lot of different companies in the space. This can make it difficult to sort through all the various offerings, but it also leads to more specialized offerings. Businesses of any size should be able to find an email marketing service that suits their business needs and improves their overall marketing strategy. To find the right service, it requires thorough research and comparisons between software you think might work best. Take advantage of the free trials that many companies offer.

Our Methodology

To find the best email marketing services, we started with nearly 90 email marketing vendors. We researched each provider thoroughly by investigating its services and reviewing features we deemed key, including pricing, ease of use, the platform's creation tools, contact management tools, segmentation tools, A/B split-testing features, analytics, deliverability and the company's customer service. 

We then narrowed down the list by eliminating vendors that don't specialize in email marketing campaigns, are not based in the United States, do not have enough information available online or don't work with small businesses. We also eliminated vendors that did not have a good online reputation as determined by online reviews and the Better Business Bureau. 

This brought our list down to 60. We then grouped contenders into each of our best pick categories – best overall email marketing service, the best service for larger business, the best free service and the best low-cost service. 

We took advantage of free trials or free versions, where possible. We uploaded contacts that included both Gmail and Outlook addresses, and designed and sent an email using the platform of each of our best picks. 

We rated each software program based on how easy it was to create the email and whether our email succeeded in landing in the inbox of our Gmail and Outlook addresses. Some emails landed in the spam folder or the promotions tab in Gmail, which we counted against the software. It's critical that businesses have their email campaigns delivered to a person's inbox. We compared the sent version of the email to the original email to make sure there were no wild, unpleasant discrepancies. As part of our evaluation, we also considered how easy the programs are to use, whether you can create email campaigns from scratch, use a template or import a fully designed email. 

Finally, we evaluated the support you'll receive from these email marketing services. We visited websites and assessed the number and quality of help resources available to clients, such as webinars, guides, and tutorials. As a busy entrepreneur, you need access to resources (often during evening hours or weekends when you have time) to quickly find answers to your most pressing questions and concerns. We also wanted to evaluate the personal touch these companies offer with their customer service. We contacted each company and posed as small business owners asking questions about the pricing and features. We evaluated how quickly we received a response to our questions and the quality of the support we received from the company. 

What to Expect in 2021

While social media and text message marketing are growing in popularity, the death of email is far from here.

According to the Email Marketing Market Research Report by Market Research Future, the email marketing industry is expected to grow at a compound annual growth rate of 15.2% through 2027. Email marketing celebrates a wide adoption rate in many different industries, including banking, financial services, consumer goods, travel and hospitality.

Despite predictions that email marketing will become obsolete, it is still widely used and will remain so through 2021. Research from Sendinblue revealed that the COVID-19 pandemic led to a bump in email marketing.

According to the research, 27% of consumers report opening more email marketing updates they get from small businesses than they were before the pandemic. While many digital marketing tools saw a bump in usage during the pandemic, email saw the highest increase, according to the data.

Email messages ranked as the overall preferred small business communication method by consumers: 30% of those surveyed ranked it as their top communication preference. Second on the list was Facebook, with 13% ranking it as their communication method of choice.

This shows that email marketing still plays a vital role in digital marketing, and there is no reason to believe that won't hold true throughout 2021.  

We also expect email marketing to become more technologically advanced, adopting more use of artificial intelligence in its capabilities. AI's primary function in email marketing will be to gather and analyze data to deliver better and more targeted experiences to customers, like specific subject lines or personalized body text. AI will also make emails more interactive by allowing customers to purchase products directly from the email, streamlining the buying journey. 

Email marketing's integration with smart devices like Alexa, Google Home, Cortana and Siri is also expected to continue growing in 2021. Consumers are getting more comfortable talking to smart devices and having them talk back, so they should soon be able to have their emails read to them in addition to hearing the news and setting reminders.
