Sorry, this has been brought up a number of times obviously, but I figured I'd still give it a shot. I'm not self-hosting email, because it sounds like a huge PITA. I was looking for a decent email provider, but coming up short for now, wonder what people here are using. My requirements:

• support for a custom domain,
• support for hooking up my applications via SMTP (just to send, like, update notifications, nothing spammy),
• (optional, but would be good to have) nice apps for Android/iOS.

Things I've tried (all paid subscriptions):

• Fastmail - felt excellent until I tried actually using it and found that 1) my SMTP messages are lost/delayed by a few hours. 2) SMTP-sent messages are not in the Sent folder, which makes things really hard to track. More details here: https://www.reddit.com/r/fastmail/comments/181tnuf/experience_with_fastmail_as_a_new_user/
• Proton Mail - doesn't have SMTP support, wat.
• Purelymail - feels a bit hackish to me, and I don't want my wife to input weird IMAP settings on her phone.

Any good recommendations? Thanks a lot!
