I'd recommend. Not sure I've found m/any other email provider that offers quite as many tools as Proton does and does it so well. Even with a free account, it's basically good enough to use for secure email with other Proton users.

Not sure all of the services warrant paying so much. Having a walle and password manager are nice features. Useful in combination with secure layered thinking, as you said.

I just really don't like the alternative of having a google/apple device, OS, email, cloud services. It's whack.
