Hey so I have been using Getresponse for giving my pdf book to customers after they pay with paypal. I beleibe I am paying too much just for using one service of getresponse so I would liek to know if there is other options. I just need a way for my customers after they pay with paypal to be able to download my book. So if there are any autoresponders for cheap that you guys no of or if you know how I can make and expiring download page that paypal redirects to that would be awsome. Thanks in advance!
