What Posteo is
Posteo is a paid email service with webmail and support for IMAP, SMTP and POP3 clients. It offers encrypted mailbox storage, integrated PGP and end-to-end encryption; incoming messages can be encrypted automatically when a public PGP key is shared with Posteo. Security options include TOTP and FIDO2 (WebAuthn) keys for two-factor authentication, along with spam filtering, virus scanning, and whitelist and blacklist controls. Posteo says it does not use data mining, advertising or behavior tracking. Accounts can be created without personal information, and cash by mail is listed among anonymous payment methods. Android and iPhone apps provide push notifications, while listed platforms also include macOS, web and Windows. The Posteo mailbox plan includes 4 GB storage, aliases, encrypted storage, an ad-free service and a Cleanup Tool. A separate Posteo plan costs €13 a month, billed quarterly, with 2 GB initial storage, 20 aliases and one active address.
