Analysis
OVERVIEW
Encrypts subject lines along with content, which most encrypted-mail designs leave readable, ships open-source clients, and allows anonymous signup on the free tier. Post-quantum hybrid encryption is deployed rather than announced.
LIMITS
German jurisdiction means court orders can compel logging of connection data for specific accounts, and paid or business tiers collect billing details the free tier avoids. Mail to outside providers still crosses in ordinary form.
USEFUL FOR
An encrypted mailbox under EU process where subject-line coverage and open clients outweigh interoperability.
