Slowly moving services away from the US. Went with Fastmail, which I used before. Was reading their privacy page only to find out they’re hosted in the US, even though they’re an Australian service.

I recommend Posteo. They are German and run on German servers using open-source software. Also highly affordable with numerous payment methods.
Been with them for years and have zero complaints.
