Fastmail is a smaller company, focused on email and calendars, but it does it well and you’re unlikely to be subject to random algorithm nukes and having to sit through the nonexistent Google support channels.
The more folk that get out of Gmail the better. Google has too much power there, and controls your entire online life by controlling your email. I’ve seen so many folks have their online lives nuked when Google didn’t like something for no real reason, then refusing to help fix it.
Fastmail does also have contacts within their portfolio and you can manage own (static) websites with their service. They do really have a great feature set.
They're the developers of JMAP (with great features for now and in future), they do have Masked Mails built-in and much more.
