One can easily define favorite groups of people for group sending, but if you wish to also include email recepients, they must manually be typed in after the group is fetched.

What about allowing individuals with email addresses to be included in the group so they can get said messages as MMS emails?

There likely would need to be a mechanism in place to discern if the message was desired to be sent just to the email or the sms, or both.

I just want to have a group with cell numbers and emails ONLY and have a message sent without more fuss... Just said group defined.
