Plugin: posts sent to mailing list address

In a few months I will be leaving to live in Russia for a year.

I am setting up an “update” mailing list address through google mx on my domain so that I can manually add those who are interested in getting updates on my trip and such.

I would like for each post I make on my wordpress blog to send to [email protected] and therefore to everyone on my list. It would also be nice to be able to have a template so that I can add information at the top and/or bottom of each post that is sent.

What’s my best bet for a plugin?
