Review on Dada Mail by Conrad Greene

It's easy to use, it has an intuitive interface for users who are not tech savvy at all! I like that my subscription lists can be added or deleted from anywhere in any page of damail without having to go back into mailman itself (i know this isn't really what you're looking for but thought i'd mention).

There have been times when there was nothing wrong with our server so we couldn't find out why some emails were "stuck" within other people's email accounts - even though they had subscribed correctly through us- which led them to believe their account wasn't working properly either!!
