I'm looking to buy advanced newsletter software that would take care of all of my newsletter needs. It should be possible to have separate databases for separate sites. I would like to add an sign up form on few of my websites and have each of them dealt with separately. The software should operate independently from third party providers - meaning that it should not be using some remote server to store the database or to send emails form. Can anyone recommend the overall best newsletter solution available today?
I am in the same position and looking for good newsletter software also. I have used Campaign Monitor in the past, but am looking for something new.
