Posteo (Berlin, founded 2009, Posteo e.K., owner Patrik Löhr) is the small-and-cult European privacy email service: €1/mo flat-rate for 4GB, anonymous signup and anonymous payment options (postal cash, no payment-to-account link kept), all servers in German data centres, 100% renewable energy from Green Planet Energy, no advertising, no profiling. BSI TR-03108 v2 certified (Bundesamt für Sicherheit in der Informationstechnik standard for secure email transport). Supports PGP and S/MIME end-to-end encryption. Publishes annual transparency reports for authority requests. The Guardian and Stiftung Warentest both cite Posteo as a global leader in secure email. Single-vendor concentration risk because of the tiny team, but for personal privacy-first use this is the cleanest possible pick.
