It meets 10 of 19 criteria: open source, no trackers or telemetry, no ads or data sales, TLS configuration, open protocols, custom domains, IMAP support, POP3 support, SMTP submission and mail transport security. It partly meets transparency report and end-to-end encryption. It does not meet independent audit, tells users about requests, security headers, encrypted mailbox storage, sign up without personal data, Sender Rewriting Scheme and ARC sealing. It is based in Switzerland: Not in the Five, Nine or Fourteen Eyes; GDPR-style data protection law. Automated tests: SSL Labs grade A and Mozilla HTTP Observatory grade D.
