Some people join everything that is free. I call it 'free overload'. Nothing wrong with going into free overload, other than often you tend to miss out on what's really important, what truly works, what is the easiest for you, and ... money.
It's best to explain this before hand, before they enroll, if at all possible. This can be done by using lead capture pages, giving a brief hint of the info, then having the viewer send for the information. You can relay the info in a series of messages.
Another idea is to have a blog or website that explains it all.
