Proton is nice, however, the high encryption component also makes it super hard to enable use cases like agentic email. That I see as a blocker for them to become really relevant.
I'd love to have a privacy-first modern mail provider, that is no Big Tech and doesn't participate in the attention economy.
The point about encryption limiting agentic is interesting. It does seem like a real tension between strong privacy guarantees and server-side intelligence.
Do you think this is a fundamental limitation of E2EE email, or more a product/architecture choice that could be worked around with different trust models or client-side approaches?
