Do you have both email address and phone number(s) for key contacts?
It may be a sign of the times but I find it increasing difficult to have both an email address and a phone number for anyone. In today's digital world, people seem determined to control where communications come from. And based on the nature of their business or as a matter of personal preference; they pick only one. What percentage of folks do you have both email and phone address for? I'm close to 20%. Is this typical?
I personally have had people reach out through my Contact me page through email. So, I am considering not having my phone number on my website at all as clients in the past have reached out to me by email. Their choice, as I had a phone number attached and it was not used by client or interested parties.
You really should have both types of contact information for "key" contacts. You might be surprised by how many people will give you both types of contact information if you directly and confidently ask them for it. If they can see that other people have given you this information, then they will more readily provide it themselves.
