Posteo is an email service provider based in Berlin, Germany, offering paid email accounts for individuals and businesses. The service gained prominence during the aftermath of the post-2013 global surveillance disclosures,[2] [3] especially for its high standard security features and relative anonymity as it does not require any private information in the registration process.[2]
Posteo offers support for DNSSEC/DANE and PGP (through Mailvelope in the web interface, which is running open source Roundcube). Additionally, they offer two-factor-authentication via TOTP, Extended Validation certificates, HPKP for the HTTPS connection, and various themes to choose from, including dark mode.[4]
In 2022, Posteo had more than 500,000 active mail accounts.[1]
