For example, I have a list for those that download my free reports from my site. I also, have a separate list for those that purchase my wso. Then I had some solo emails sent out and created a separate list for that because I knew those in that list were mainly into offline.
Anyways, I've got 12 different lists now and starting to regret it, because it's a lot of work to manage it and set up the autoresponders.
How is everyone else doing this? Did you build multiple lists or just one?
