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.
They’re also hosted entirely in Germany, and really transparent about how many government requests they receive, most of which they outright deny.
Also, you can pay by literally mailing them cash, which I find mostly funny, but it does allow for true anonymity.
