Secure Email Provider Posteo: Privacy and Sustainability from Germany
Since the 2013 global surveillance disclosures, email users have sought alternatives to mainstream providers that track and monetize data. Posteo, based in Berlin, Germany, emerged as a response. Founded in 2009, it now serves over 500,000 accounts without requiring personal details for signup or logging IP addresses. This German service emphasizes data minimization, robust encryption, and environmental responsibility. Servers run on 100% green energy in data centers across Frankfurt, Bielefeld, and Berlin. Posteo avoids advertising and tracking entirely, offering a straightforward paid model starting at 1€ per month for 2GB storage, expandable as needed. Features extend beyond email to include a calendar, address book, and notes, all accessible via open-source Roundcube webmail or standard protocols like IMAP, POP3, and SMTP. Its commitment to transparency includes annual reports on law enforcement requests since 2014, a first in Germany.
What is Posteo?
Posteo is an independent email provider started in 2009 by Patrik Löhr and Sabrina Löhr in Berlin. It gained traction after Edward Snowden's revelations highlighted mass surveillance risks. Unlike ad-supported giants, Posteo charges a flat fee—no free tier—to fund operations without user data sales. Headquarters remain in Berlin, with a team of over 40 employees. No business flights since launch, an organic vegetarian canteen, and efficient servers underscore its sustainability pledge.
Servers use full-disk LUKS encryption and open-source software. Posteo was audited favorably by data protection authorities and won tests by Stiftung Warentest in 2015 and 2016, plus the German Fairness Award for 2024/2025. Innovations include DANE/TLSA support as Germany's first provider, TLS delivery guarantees, and app passwords. Users can pay anonymously via cash or crypto, reinforcing its appeal for those evading tracking. Storage begins at 2GB but scales to 20GB or more. Spam and virus filters handle threats professionally. While not end-to-end encrypted by default, optional "crypto mail" encrypts emails and metadata with a user-derived key. PGP and S/MIME inbound support, plus Mailvelope integration, cater to advanced needs. Two-factor authentication via TOTP adds protection. Posteo promotes open standards and digital rights without business models reliant on surveillance.
Who Uses Posteo?
Posteo attracts privacy-conscious individuals wary of data-hungry providers. Journalists use it to shield sources, given no logs and anonymous signup. Activists rely on its resistance to surveillance requests. Businesses adopt it for ad-free, secure team communication without tracking. Professionals in regulated sectors value GDPR alignment and audit trails. It's suited for personal use too, with family sharing options. While no high-profile customers are publicized to maintain privacy, its 500,000+ users span Europe and beyond, drawn to alternatives amid rising cyber threats.
European Advantage
Headquartered in Berlin with servers solely in Germany, Posteo benefits from strict EU data protection laws. Full GDPR compliance ensures data sovereignty—no U.S. CLOUD Act risks. German authorities oversee operations, and transparency reports show limited, lawful responses to requests. Proximity reduces latency for European users. The Berlin team understands regional privacy expectations, prioritizing open-source and minimization over profit-driven surveillance.
How Posteo Compares
Posteo differentiates through anonymity: signup needs no name, phone, or recovery email; cash payments possible. Unlike Proton Mail (Switzerland-based, free tier, default E2EE but signup requires some verification), Posteo skips personal info entirely. Tutanota (also German) offers automatic E2EE but mandates an email for signup. Mailbox.org provides more business tools but less green focus. Posteo leads in sustainability and optional encryption flexibility, ideal for users wanting control without defaults. All share strong privacy, but Posteo's no-tracking, green ethos suits purists.
