Does anyone have any experience with http://ezinemanager.com?

All comments good or bad is appreciated.

How would it be different than a good mailing list manager like MojoMail?http://mojo.skazat.com/

I sort of thought the same thing, but I had a client ask about it and I had never heard of it. So I thought I would toss it out to see if anyone has any experience with it.
