Newletters & Archive

I am in need of a module that allows an Admin role to send different emails/newsletters to registered members, and then archive them.

For example, the site I'm working on is for a non-profit. The Director sends out an informal update to the association members every week. I need to enable a form to send these and have the sent messages archived in a "Notes from..." heading. She also does monthly newsletters and infrequent legislative updages, each of these would have to be archived under a "Newletter" and "Legislative Update" heading.

I noticed the Mail module, but it doesn't quite look as robust as I need. Am I wrong? Any suggestions in configuring something like this?

Thanks!!!
