Slowly moving services away from the US. Went with Fastmail, which I used before. Was reading their privacy page only to find out they’re hosted in the US, even though they’re an Australian service.

I don’t want to influence you but take your time and compare every other option. Mailbox is the clunkiest and ugliest UI I’ve ever seen. Their 2FA feels like a dirty hack too. I’m sure they’re good technically though.
They support IMAP, right? That’s really all I need.
