The E2E will help so long as you're sending email to other users of the same service, yeah. For most cases, it's probably not a huge upgrade from stored encrypted; the bulk of damage in email leaks would be from accumulated emails from the past.
The reason I don't recommend using it if you're super paranoid is because it'd be easy to mess up, and it comes with quite significant holes- e.g. subjects aren't E2E in Protonmail. Best to use a protocol designed for E2E from the ground up.

- piaste 5y agoTutanota went with a different tradeoff so they have E2E encryption of subject lines etc. Downside is that they can't support other clients, which is why I wouldn't have even considered them if the apps hadn't been open source. https://tutanota.com/secure-email/ https://tutanota.com/secure-email/ They also have a pseudo-workaround for using E2E with external users - if I send a secure message to foo@bar.com, I can encrypt it with a pre-shared password and their mail will get a link to a web "mailbox" where they can enter that password to decrypt the message. Clunky, but I wouldn't know how to do better.
