Do you mean a composing tool, or a sequential auto responder, or do you mean an email response tracking system?
Any HTML editor will work, dream weaver is fine, an open source equivilant is Nvu: http://nvudev.com/
I struggle with nvu because it's very style orientated and for emails you need to ditch css and go for font tags etc. BDazzler - If you know a way to make nvu go "old school" I'd be very interested.
Good point. I'll tell you what you could probaby do. I bet you could find an old copy of Dream Weaver 2004 MX, that's the version I stlll use, on EBay. (Just Guessing) I KNOW that works.
