I've gotten a lot of good feedback by sharing some videos with my list. Even a simple video made with a cheap little webcam of you talking about the same subject matter mentioned in an email newsletter helps your list feel like they know you even more.

The next time they read a message from you they'll remember seeing that video of you talking and the words will now have a face & voice to go along with them, which should in effect make your readers feel like they know you much better than someone who they've never seen or heard before.
