I agree. Their spam filtering is absolute trash. I get 3-4 spam messages a day in my inbox. I file support tickets for it and they always tell me there is nothing they can do.
Uhh, I don't know about that. Since getting airtags I've misplaced my car keys multiple times, left my wallet on an airplane, and had multiple airlines misplace my luggage. In that same time I've not had anything stolen.
I agree with you on the UI, but left Fastmail and went back to Google workspace because of Fastmails poor spam filtering. 1-2 pieces of spam were hitting my inbox daily. On Workspace it's 1-2 a month.
