Use business envelopes that are machinable or qualify for automation Machinable envelopes must be rectangular in shape and a minimum of 5 inches long, 3.5 inches high and 0.007 of an inch thick. Maximum dimensions for customized envelopes are 11.5 inches long, 6.125 inches high and 0.25 of an inch thick. These envelopes cannot exceed a weight of 3.3 ounces. If your envelopes meet these standards, then they are eligible for presort rates. Automation envelopes, which are machinable and have a delivery barcode, have even cheaper rates because it takes even less effort for the post office to sort them.

I recommend:  Purchase the Postnet font from Postage Saver for your word processing program for DIY implementation of the appropriate automation delivery barcode on your envelopes. Programs like Corel’s WordPerfect give the option to insert the delivery barcode when using the envelope function.

Plan for extra charges when your mailing envelopes are nonmachinable Envelopes that fall under the nonmachinable category are subject to an additional charge by the postal service. Nonmachinable mail contains items such as pens, buttons or coins that cause the envelope dimensions to be uneven. These envelopes weigh more than 3.3 ounces, have a plastic material enclosure and close with the use of clasps or stings (such as manila envelopes), among other criteria.

I recommend:  The USPS provides further detailed information on the requirements for your envelopes to meet any of the three mail classifications. Clearbags offers clear envelopes so that potential clients can see the contents, which the USPS has approved as nonmachinable mailers.

Find envelope manufacturers that provide products that meet USPS requirements Most envelope suppliers and manufacturers provide all possible options for your envelope needs. Stick with size 10 envelopes, which generally meet machinable requirements, for all of your regular mailing needs, such as invoices and letters. This will help save your business money on postage.

I recommend:  Visit Action Envelope to shop for envelopes by use so you will find the right envelope for your mailing needs. Jam Paper & Envelope also provides a large variety of envelopes to choose from, in all sizes and colors.
