Do you think it is still necessary to build your list through traditional e-mail marketing?
The reason I ask is, more high-end marketers are concerned with building fans and followers, because they realize people are hanging out on sites like FaceBook, Twitter, linkedin, and Google+
Also recent statistics (I forget the exact percentage) are showing the traffic from these sites are responding to marketing offers way more than than email.
So is it even necessary to keep an auto-responder ?
PS I already know these platforms can just close down one day, or saturated, or you can get banned, etc... and you can still fallback on the list you created.
I think I am looking for other other reasons why it would be necessary for me to keep building my list with an auto-responder.
