I was considering Protonmail (have a paid subscription for many years even) but that is e2e encrypted, which means searching emails needs a local index of all emails. I have many many years of emails and several client apps. So that is not an option for me.

Therefore I wonder if this is different (‘better’) for Fastmail. It means Fastmail also can see the contents and that is ok, I just want to move away from US providers.
