PHP Newsletter Web Application

[matdjj]

Hi,
I have an email mailing list of 20,000+ users and am looking for a web application to handle everything related to sending newsletters out. Does anyone know of any good PHP web applications that can do this?

My site is running on a dedicated server with mySQL databases available.

Thanks!

So you're looking to spam 20,000+ people. Try search hotscripts or create your own, then post in the php forum for php help

This is far from spam, every user has either registered at one of our international televised events and has requested the newsletter. I am hoping that someone else has some experience with some good web apps that they can recommend. They do not necessarily have to be free.
