Just use any other email service that works for you and use OpenPGP to encrypt your emails.
Also if whoever you are emailing isnt using protonmail, then you arent actually getting any more security than with gmail.
For work emails the other party usually wont be using encryption, for personal stuff you should use standard messengers that have encryption built in like matrix, signal, session.
If you want e2ee email tho, then on desktop Thunderbird has everything you need built in and for mobile there is the K9-Mail client that can be coupled with the openkeychain plugin to offer encryption.
There are also things like DeltaChat that allow you to use email in an instant messaging style format while using the same encryption keys that you use for standard emails. But tbh thats not what email is intended for, i would just use matrix for that.
Protonmail is a decent attempt at offering “easy to use” encryption but by doing so, makes it overly complex from a software security and compatibility standpoint.
With end to end encryption you want to have the absolute minimum level of complexity and code to make it easy to audit and understand. PGP has been the standard implementation for email encryption for decades. Any attempt to “expand” on this by implementing fancy web based shenanigans undermines the simplicity and inter compatibility of the preexisting email encryption ecoystem that everyone has been using.

Thanks so much for sharing! You gave me some good info to start looking into. I appreciate your help! I was getting a little weary of Proton when they announced the AI nonsense and now the crypto wallet really seals the deal. Doesn’t feel good knowing my money is going to develop buzzword features instead of fixing the existing issues in their current products.

Good luck with your software endeavors!
This stuff is hard to get into, especially so if you don’t already know all the specific terms to find what you are looking for.
