I have been doing some searching to try and find a web based program for managing multiple mailing lists / newsletters. About the best I seem to have found so far is SubscribeMe Pro, but I was wondering if anyone has found anything that is database driven (ie, mysql), create special unsubscribe links that can be included in the email messages, personalize messages, track clickthroughs on links in the outgoing messages, possibly integrates with something like procmail for handling bounces and finally would allow the admin to set up other "list managers" that could run their own little newsletter and set certain parameters on things like how often they can email people, etc...
