What other free options are out there? Proton Mail’s free plan restricts to only 3 folders.
EDIT: After careful discussion with others, I’ve reluctantly decided to stick to Gmail, because we don’t know if these other providers will still be around 50 years from now.
I signed up to Disroot a few months ago. The free option supports IMAP, which is what made it for me. It’s also more than just email (they have stuff like a pastebin and even a Forgejo instance)
