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 use it as a secondary email (Proton is primary).
Works great and IMAP support isn’t necessary for me. Also I like Tuta’s UI way more than Gmail’s or Proton’s.
