I almost signed up for Gaggle Mail even though it's US-based. I figured at least they seem to have good sense in seeing the value of email for discussion groups. And then while trialing I saw they have a function to summarise email discussions via ChatGPT that is turned on by default. I mean, wtaf.

So I'm deciding on self-hosting Mailman. It always seems to come back to self-hosting in the end, doesn't it… which is not nearly easy enough for most people to grapple with.
