I’ve been happy with Fastmail.
The cost isn’t too bad at $5/mo per user.
The wildcard email thing is cool. You can use addresses like whatever@user.domain.tld to hand out to companies on the fly.
I may go back to hosting my own, but I have no complaints with Fastmail at all.
I think the lesson to be learned is that everything works in the demo (except when it doesn’t), but when it’s deployed to thousands of sites by the cheapest contractors, operated by untrained and unmotivated personnel, and not calibrated or maintained over its lifetime… the reliability goes down a bit.
