What's a good alternative to Proton? Still haven't migrated my business away from Google Workspace, and I was thinking Proton would be a good alternative, but apparently not if they don't even support IMAP/SMTP.
Mailbox looks very solid, although I don't have long-term experience: https://mailbox.org
It provides email, online storage, video conferencing, calendar etc., all of it privacy-preserving by default. You explicitly don't have to provide any personal details.
Fastmail[0] is what I use for my personal email. They support all the standards, but are also pushing things forward with standardising the JMAP protocol[1] which is much better suited to mobile clients than IMAP.
They only have email and calendaring though, no equivalent of Drive/Docs/Sheets.
Australian businesses have to provide GDPR protections to EU citizens, regardless, just as EU companies operating in Australia have to obey Australian law.
I also have a feeling the Five Eyes agreement is about to end.
Not mailbox.org (!) unlike many have suggested. In last few years mailbox has gone into the gutters in almost every aspect (almost) - I am stuck there because of a large recharge/purchase I had done and they don't do prorated refunds anymore.
There are other options - tuta, posteo, runbox etc (I have just made a longer comment and I am sure you can find more on the net).
IMHO - we should not ignore other things when looking for a service replacement I mean aspects of a service other than privacy and for me responsiveness and customer service comes near the top or at the top.
