Whoa. Crash Bang.
Talked to two people in the last couple of weeks who hadn't owned their own list. Both of them shared stories where their upline (relatively big name too) had stolen (harsh word I know) people from them and introduced them to a higher ticket affiliate program or into their own company. The excuse? They weren't educated enough yet to handle that lead.
If you do not own your OWN leads (you know all the work that YOU put into getting that lead for YOU) then think twice about what you're involved with.
If they are sending out emails on your behalf - you don't own your list !
Don't give your power away !
