So, I moved to Fastmail in 2016, and I'd say I've never had to get a legitimate email out of my spam folder, and I've never seen obvious spam hit my inbox. I do occasionally get the "my husband left me five mil overseas" type garbage, it's always spam-binned correctly. (Meanwhile, my Gmail account I retain in case someone tries to reach out to it, regularly has emoji-subject-filled spam and other garbage Gmail fails to classify, and also has a deluge of garbage spam coming in... at this point, Gmail is 98% spam for me?) One important point here, and I don't know how long you used Fastmail when you tried it, is that Fastmail uses a personalized spam filter. It probably took me six to eight months to receive enough spam on Fastmail to actually train it. (In the interim, they use a non-personalized filter, which as I said, still worked!) Gmail doesn't seem to be able to make personal spam decisions: When I was regularly using Gmail, some types of regular messages would spam-bin no matter how many times I marked them not spam or classified them as a particular category of mail.
