I used to use BlueHost and they had a small email list function built into the CPanel.

Do you guys not offer something similar ?

I have installed PHPList, where this will be nice for a newsletter, it does not supply the service that I need.

I need two email lists, one with up to five addresses on it, and another with support up to 15 (in the coming years).

This seems like such a simple request.
I am hoping I am missing something.
