> I suspect Protonmail is as easy to use as GMail.

End-to-end encryption without a trusted server makes multi-device usage rather complicated within a number of contexts. Full-text search for example then requires all your e-mails to be indexed on each individual device you're using for accessing Protonmail, and you need to keep that index permanently unless you want to re-download all messages and re-index them again the next time you need to search something.

I don't very frequently use full-text search from my phone for example, but when I need it, I do need it, so neither proposition (permanently occupying valuable space on my mobile phone with a search index I only occasionally need, or else wasting a noticeable amount of time and data volume to re-index all mails every time I want to search something) sounds really enticing.
