I looked at Fastmail and many others when I made this switch at the end of 2018. I moved my whole family's email setup from google. Fastmail is based in Australia, which is a five-eyes country so I ruled it out (sadly, as would have loved to use it). I wrote all of this up here: https://www.gtf.io/musings/moving-away-from-google-email/
Spoiler: ended up using Runbox (www.runbox.com). I disagree with them on this but I think the webmail UI is pretty crap. I don't use it though, and instead use neomutt (on Linux) and Apple Mail (on iOS). I've found it to be pretty reliable and the support is very responsive.
