Or google groups? https://gist.github.com/adamamyl/02a8f44981c8685f9c88 reminds me of https://mail.python.org/pipermail/mailman-users/2014-October/077893.html
Thanks for the suggestion. I've actually already tried that. It was my first thought. I found a Python Google API which looked straightforward to use, but I could never figure out the whole setup/authentication process, and my pleas for assistance on the (I think appropriate) Google help forum, yielded no help, so I gave up.
I will take a look at your links.
