I'm looking at Tuta. It's not free (well, they have a crappy free tier), but it's cheap, is end to end encrypted (as much as email can be), has extra address support, and supports custom domains. So if I hate it, I'll switch to something else (maybe ProtonMail). The initial switch from my Gmail will suck, but it'll hopefully be a one-time thing.
