So in an nutshell I want to launch a product. Here is how the plot goes... 1. User goes on the website 2. User reads the website 3. User clicks "Buy Now!" 4. User Buys the product and automatically signs up for a $7/month subscription (user is aware of that) 5. User is then taken to a page where he can download the product 6. Once a week the user gets an email (by chronological order, so no matter when the user signs up, he will still get the first email, 2nd, 3rd, etc). 7. If a user typed in their email wrong, they can email me, and the email will be changed So you know... seems pretty basic, I guess? But here are the questions 1. What software do I use to make the transactions with the users? 2. Does the software support subscript services? 3. Can I go inside the software and change the email the subscription goes to? 4. Does the software support the chronological order email subscription? 5. Doe the software support email change? 6. What software do I need to collect the emails when they sign up?
