make a phone-number-hyperlink option so people who read the email on their phone can click the phone number in the email to dial
When creating a Form Letter/HTML Form Letter to be used as email, make the phone number a link to dial, for users that open the email on their phone
This feature is actually already built in to most mobile devices. Client’s phones will automatically recognize a phone number and turn it into a clickable link.

This is a great idea

and of course, it should work in a form-letter SMS Text message too.
