When switching mail, more things count than sending new messages. Think of existing folders, contacts, recovery options and the devices on which your mail is read. Check which access and functions your subscription supports.
Verify important addresses and view attachments critically, also in a secure mail service. Protection of saved messages does not prevent phishing. Save recovery data safely and test the login on your main devices before switching completely.
Version and updates
Check for Proton Mail the version number of the release you are actually installing. The versions for Windows, macOS, Linux, Android, iOS, Web do not have to run the same.
Compare Proton Mail with alternatives
First check your account type, calendar, contacts and the way in which you store local folders. You can often synchronize IMAP mail again, but local archives and filters require extra attention when switching. Support for a mailbox does not always mean that all group functions are taken over.

Our verdict
Proton Mail fits if you consciously choose this mail service and its security model. First test import, search and collaboration with your existing devices. Keep recovery data carefully. For use in Outlook or Thunderbird you need to review Bridge terms; a Proton account does not behave like any ordinary IMAP mailbox.
