I have been recently looking at some websites and they have a mailing list newsletter. If I click unsubscribe it goes straight to their server and you can unsubscribe from their server.
- What tools do they use to manage this? I was thinking of something like Constant Contact, but with Constant Contact you have to go to their page to unsubscribe from their mailing list.
- If big websites use their own servers to send out these mailing list newsletters, wouldn't they need some 3rd party software to handle so many emails?
- What is the best way for creating something like this that's on my own website? (aka they can go into their account and disable newsletters and it will automatically not send them emails, but it takes place ON their website)
