Green energy, zero surveillance: How Posteo powers a private inbox
Posteo, founded in 2009 by Matthias Heine in Berlin, Germany, is an independent email provider rooted in strict German and EU privacy laws, including GDPR.
It guarantees no advertising or data mining, allowing users to sign up anonymously without a name or backup email, with payment options including cash. The service mandates server-side encryption for all stored data and offers an optional “crypto mailstorage” feature to protect messages even if servers are compromised.
Supporting standard protocols like IMAP and SMTP, it also enables PGP and S/MIME for end-to-end encryption.
Uniquely, Posteo operates entirely on certified green energy, combining robust digital privacy with environmental sustainability for a truly ethical, surveillance-free inbox.
