> search in Proton Mail is so bad I couldn’t use it for even simple things like finding my airline tickets.

Not sure if it's related but

  Proton does not hold your unencrypted email body content

consequently only you do once you are logged in. Thus you can't have server side search on your email content, only on email title. What you can have though is client side full-text search on body content. For that you have to enable it via the search box, details https://proton.me/support/search-message-content

It's not perfect but obviously it's a LOT more than searching only on titles.

Protons email encryption is mostly snakeoil and marketing. Their guarantees of strict encryption at rest is really only relevant to a certain class of people with a very specific threat model. Everyone else that uses the service is just leaking plain text email with everyone they converse with who uses a service that does not offer the same encryption guarantees.

So basically they sacrifice a usable search function for a security service that isn't relevant to 99% of people and isn't even effective half the time.

FUD much? Snakeoil would be false claims. There are plenty of problems with Proton but AFAIK not genuinely encrypting customer data is not one of them. If you do have examples please do share.

Marketing that might not address the average user who still get in touch with people relying on surveillance capitalism like GMail address sure but bundling both as one is dishonest IMHO.

Yeah I tried it and it was still unusable. I barely noticed any improvement.
