I just watched a tutorial. It says that if someone buys your front offer you should take them off your "freebie" seekers and put them on your "buyers list". If they then buy your upsell you should move them to another subscriber list (making a new subscriber list with the upsell they bought) in your auto-responder. Then do the same if you have a second upsell offer.
This means what to you fellow Warriors? why do you need to put them on a different subscriber list if they buy a product?
These bottom 2 questions are kinda the same:
Do you keep them on the same email campaign with your regular sales funnel offers through emailing?
Do you keep them on the same email campaign even if they are put on an "upgrade" subscriber list?
