RoR: Mailing Lists?

Are there any gems or plugins out there that make managing mailing lists (just for updates and announcements; not marketing... ie, MailChimp is overkill) easy to administer?

Or is that just something that most Rails developers just build from scratch?

Just curious.

Don't think there is, because it's too easy to make from scratch, just MailingList habtm MailAddresses :)

Anyway the GUI you'll need to build from scratch.

So the question is what functionality do you want a mailing list to have...
