I have a user registration based website and desktop app in beta testing. I only have a small number of users, but am beginning to plan my email list practice to cater for a larger list.
I have a couple of questions if anyone experienced can help out:
1. do user registration sites with a reasonable sized member base typically use services like Get Response, or do they somehow use an internal system?
2. at the moment I'm planning the code that will let users change their details, such as their email, and it occured to me that if I did eventually use an email service as mentioned above, how does such a service keep track of an action such as a user deciding changing their email address on your website (using php and mysql)?
Thanks for your time and help guys.
