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.
Furthermore they use Greenpeace Energy (a renewable energy company) in order to keep alive their mail servers, which is one more reason that differentiates them from the others :). This is what keeps me from going elsewhere yet again.
