Given the great community of developers it seems strange that such a toolset as Mambo does not have a stable Newsletter Component
Letterman - on hold seeking a new leader
MAMML - Based on YANC - All sort of issues here and no real direction or stability
Simple HTML newsletter - no activity
There are discussions about wrapping other newsletter code but I'm not sure about why we can't seem to get this right.

Mambo ... a great system receiving accolades ... but hey we can't communicte with our registered members in a professional manner.
I have two web sites that we send the same newsletter to so we're dragging the emails from the database into one non Mambo system, how primitive.
What concerns me is we're about to launch two new sites for clients --- one 25,000 subscribers the other 15,000 in three sub groups ... both non profit groups.
I need something which integrates with the Mambo registration system and actually works with these sort of figures.
Other than that is there any way we can (without going into mySQL) export the registrant details in a format so they can be imported into another system?
I'm looking for a solution that actually works and is integrated with Mambo for people with out access or understanding of technical issues once implemented.
