Their comparison of themselves to Proton is rather deceptive. If you're willing have only 1GB of storage, instead of 3GB, you can get proton for free. And at the price they list ($48/yr), you'd get 15GB storage, plus a lot more. And no, I was not paid by proton to say this. I only have the free plan.

This claim is also rather deceptive because the free proton mail does not allow custom domain. To get your own domain with proton you have to get 4usd/month plan.

Proton does not allow you to use standard protocols (IMAP/SMTP), which is a deal-breaker for me.

They have a bridge app for normal protocols, though I have had problems with it losing content IDs on attachments

Protonmail doesn’t support IMAP which is something wish I knew before migrating
