The email lists I download are from a program I belong to, don’t receive them thru e-mail. Tho I have some I do get e-mail and I need to upload them to my autoreponder in a csv file to.

I would like to add a section to my website, where a person can pay for the product, and upon payment, they can click on a link to automatically download the information they purchased. I have used several sites using this, but have not been able to find out how its done. Any tips or advice appreciated
