I am looking to create multiple Mailing Lists, one for every PayPal "Buy Now" button. The goal is to have the customers email address be automatically added to that specific PayPal item Mailing List when they check out. I am using cPanel which has a Mailing List option. My understanding is that cPanel uses mailman, which I think uses file system, not database tables, which is fine but I do not have as much programming experience as I would like. So, using cPanel may not be a good option. I do not care what Mailing List program is used, I would just like for it to work well and be secure. Thanks in advance for the help.
