Great points, thanks.

Can you clarify what you mean by “local decryption”? I thought Proton and Tuta work pretty much the same way, but perhaps there’s a distinction I’m missing.

One thing I like about Tuta is that it has the option to cache your messages in localstorage in your browser so you can do full-text search. FWIW, I think Proton added a similar feature recently, though I have not tried it. I imagine neither would work very well with large mailboxes; probably better to configure a real email client.

Do they offer cloud storage now? From what I can see on their web site, it’s 500GB…just for email. I mean sure, that’s cool, but it would take me several lifetimes to accumulate 500GB of email so it’s not much of a selling point to me.

It’s a good email service, anyway. I’ve been using the free tier for a few years. Similar to Proton, and in theory Tuta is more private because they encrypt the headers as well as the message body.
