Posteo email service

Posteo is an independent German email provider based in Berlin, known for its strong emphasis on privacy, security, and sustainability. Launched in 2009, it offers ad-free email accounts funded entirely through user subscriptions. The service is notable for being powered by green energy from Greenpeace Energy and maintaining a strict no-tracking policy.

The company is privately owned and has resisted acquisition attempts to maintain its independence and commitment to user data protection. All servers are located in Germany, governed by strict German data protection laws. Posteo is often cited as a pioneer in providing anonymous payment methods for digital services, allowing users to pay via cash or bank transfer without linking their identity to their email account.
