I have an account and I love the product.

But the big drawback is that you can't really search full-text in the body of emails because of encryption on server side. And searching in the subject is most often not enough.

I really wonder how people deal with that.

If you don't have many emails in your archive, you can use their web storage full-text search, but that's not scalable.

You can also use Proton Bridge with Thunderbird to import your emails locally and search full-text, but that's not handy through multiple desktops and mobile.

So you're left with over-engineering your email subjects, labeling and folders, which is not manageable.

I'd love to give up on Gmail and go 100% ProtonMail but I need to solve that problem first.
