That was what kept me on GMail for so long. But about a month ago I moved several accounts to FastMail (at the urging of others on HN), and have been pleasantly surprised by the results.
FM seems to have a lot fewer false positives, and the amount of spam that gets through seems only marginally more than with GMail.
FM offers a 30-day free trial, which even includes using your own domain. That I found surprising. Usually trials so restricted you can't really get a sense of what you're getting into.
It doesn’t look like they’re doing much beyond what I did 10+ years ago when I was running high volume mail servers and it was never enough: https://www.fastmail.com/help/technical/spamchecks.html
Make the move away from Google, don’t be scared and don’t be guided by false excuses.
That's $500-$1000 a year on Fastmail's Standard plan, the lowest tier plan that allows you to use your own domain.
Im not really interested in managing everything that I perceive goes into managing my own email server (ip reputation management and having to keep a box online 24/7)
This myth that nobody but Gmail can handle spam needs to die. It was true in 2006, but it is not true in 2019.
