What I don’t like about Proton is that I can’t combine Mail Plus and Pass Plus. I don’t need a 500 GB Proton Drive or Proton VPN, but I like their Mail and Password Manager. Now I use Mail for free and Password Manager for €12/year. I would like to pay €3.99/month for the Mail offer, but for that I would have to upgrade to the much more extensive Proton Unlimited.
