Hello, I would like to get some guidance as to what is the best way to implement a newsletter sign in system for a website.
My questions revolve around:
â€¢ Open source software vs paid ones.
â€¢ Should I use MySql or just write the emails to a text file.
â€¢ Do you really need to have the user opt in twice to be on the safe side.
â€¢ What solution have you implemented and are happy with.
â€¢ Which have you implemented and is simply the wrong way of doing it.
â€¢ Any simple tutorials to implement it.
