Posteo is an independent email provider based in Berlin. We offer anonymous and sustainable email accounts, address books and calendars. Our service is completely ad-free and self-financed. Posteo was founded in 2009. We want to provide an impetus for greater security, privacy and sustainability on the internet, and offer alternatives.
Posteo is for all who have had enough of companies that collect data, inboxes polluted with advertising and all-pervasive surveillance on the internet. It’s also for those who find it important to act sustainably in terms of both ecology and economics. Our concern is to protect your personal information, not to sell it to the highest bidder from the advertising industry. For this reason, we do not collect your personal information, do not use tracking tools and make daily back-ups. Posteo is equipped with an innovative encryption concept. We always encrypt your data with the newest technologies – and promote wider use of open standards. We actively support digital civil liberties: In May 2014, Posteo became the first German telecommunications service to publish a transparency report.

Posteo has a comprehensive concept of sustainability. We work using real green energy from Greenpeace Energy, not (so-called) “certified energy” from old hydro-electric stations, which other providers term green energy. The use of efficient hardware and recycled paper is self-evident for us, as is our bank account with GLS Bank. Sustainability page >>
Since the NSA scandal became public, our service has often been recommended in the media and evaluated by various computing magazines. Press reviews >>

Our offices are well-lit and set up for functionality. All of our desks are custom made from FSC wood. Shelves and cabinets are from Werkhaus. Each purchase is checked for its environmental credentials.
Each day, we offer our employees a free, organic-vegetarian lunch, for which Posteo employs its own cook. Drinks, fruit and sweets are also available to the Posteo team at no cost.
The Posteo Lab is a meeting and event space in Berlin’s Kreuzberg. In the lab, you can try out Posteo, add credit and take part in individual encryption training . In addition, there are sustainable products such as the Fairphone and Fair Mouse on display. The lab itself is also sustainably set up.
We regularly open the space for lectures, functions, training and cultural events. Information on current events can be found in our events calendar.
We make the lab available to external organisations free of charge. The events should fit with Posteo and themes relevant to Posteo. Interested parties can contact us by email: veranstaltungen(at)posteo(dot)de.

The site of the old Schultheiss brewery is the highest natural point in inner-city Berlin: the hill known as Kreuzberg. The brewery joins with Viktoria Park, from where you can see out over the city. A short way down the street is a plaque to mark the place where Konrad Zuse built the "Zuse Z3" – the first digital computer in the world.
Our servers are located in data centres in three German cities – Frankfurt, Bielefeld and Berlin. They are powered with 100% energy from Greenpeace Energy. All Posteo servers exclusively use open source software, for security reasons. The hard drives are fully encrypted using LUKS – and all connections between our servers are encrypted. Further information can be found on our sustainability page and our encryption info page.
