Non-profit organizations (NPOs) need office tools - just like any other business. However, as they use their time and money not to make profits but to improve our society, they should be able to use these tools for free. That's why we have partnered with Stifter-helfen and tech-soup. Now, NPOs can get Tutanota Premium for free!

The Internet as we know it is a magnificent space where everyone has the right to share their thoughts freely. However, people living in dictatorships experience a much different Internet: Censorship, blocking of major sites or social media platforms are normal to them. If we allow Internet Service Providers (ISPs) to decide what content they want to show us and what content they want to block, this is exactly how we can expect our future Internet to look like. To protect freedom of speech and democracy, we must fight for net neutrality now.

We are excited to announce that we have added a dark theme to our new Tutanota client. At the moment the new client is still in private beta. But as we have fixed a lot of bugs now, this release is a big step towards the public beta release later this year.

Everybody knows that data protection laws in Germany are very strict, and that German companies are compelled to protect their users' data by law. Nevertheless, also in Germany politicians call for access to users' data to prevent crimes such as terror attacks. This is heavily debated in the media because of Germany's history with state surveillance (ie. the Stasi in former East Germany). While this discussion is much needed to stop the authorities from getting excessive access to citizens' data, it also makes the situation confusing. This post sheds some light into the current situation of data protection laws in Germany.

Tutanota, the world's first end-to-end encrypted mail service, has recently joined the Open Invention Network. Tutanota joins companies such as Google, IBM, NEC, Red Hat and SUSE, who are all part of OIN. OIN enables open source developers to freely develop and share their work while being protected from patent suits. All members of OIN have joined to voice their support for the principle of non-aggression. We at Tutanota are happy to be part of OIN and to do our share to support and strengthen the open source community.

Phishing is one of the most common attacks on the Internet, but it is also very easy not to fall for phishing. Here are some easy steps how to prevent a phishing attack from being successful. Most importantly: Never share your password.

The encrypted mail service Tutanota helps over two million users to share their mails securely - also with attachments. However, when the attachments get too large people and businesses need encrypted cloud storage as well. We've spoken to Istvan Lam, CEO of Tresorit, about our shared goal to make end-to-end encryption a tool to be used by the masses.

Your connection to Tutanota is protected with an extended validation SSL certificate and Perfect Forward Secrecy. In addition your secure Tutanota mail supports DANE. The DANE protocol effectively protects against MITM attacks and should be implemented by all mail providers.

On April 3, 2017, President Trump signed a bill which was designed to cut out all of the FCCs protective laws for consumer internet use in the US. This action effectively opened the floodgates for advertisers and increased the reach of government procurement on data generated by private citizens.

Our website will be down for server maintenance for about eight hours starting at 10:30 PM (CEST) April 4th. Your encrypted mailbox will still be accessible via app.tutanota.com or via our free and open source Android and iOS apps.

Secure mail service Tutanota is now being used by over two million people around the world to encrypt their private communication. The more people use Tutanota, the more write reviews about our encrypted mail. Check out these reviews about Tutanota!

Google has pulled out of E2EMail last week, making it very unlikely that automatic end-to-end encryption will ever be available to millions of Gmail users. It seems as if for Google promising real encryption was only a marketing move after the Snowden revelations in 2013.

Now that the Trump family is using encrypted Tutanota emails, the NSA is deeply saddened by the fact that they cannot read Trump's emails anymore. Reliable sources report that the NSA is looking into alternative observation methods to monitor Trump's communication. Now, for the first time, the NSA has deployed radio chips secretly inserted into the POTUS' brain.

This week well-known German journalist Christian Stöcker posted a commentary with a rather terrifying thesis: Only the bad relations between Trump and the NSA are currently stopping him from abusing the NSA to use this surveillance apparatus for anti-democratic purposes. The US authorities need to prevent him from using their tools to oppress the press and political opponents.

A couple of months ago we introduced the option to buy additional storage when you need more than the 1 GB that every account gets for free. While we trusted people would be honest and upgrade voluntarily, we had to learn otherwise. With this update we enforce the storage capacity limit for every mailbox.

With this update we have significantly improved spam handling by adding DKIM and DMARC to Tutanota. In addition we are changing our support system. Up to now we have answered all support requests. However, with well over one million users, we need to put more time into development than answering innumberable emails every day.

Five years ago we have started our journey to create the most secure email service. Today we see that a growing number of people around the world are turning to encrypted email because they understand the value of their data. This gives us reason to celebrate because only with strong end-to-end encryption we can protect our right to privacy!

Every second person already distrusts companies in using their personal data correctly. Interviews done by Boston Consulting in Europe and in the USA show that this figure could grow immensely as more and more data breaches become public.

In Germany journalists uncovered that the browser add-on Web of Trust (WOT) saves users' surf history to sell this data. While the company claims that the data being sold is anonymized, the journalists were able to identify several users, among those journalists, judges, policemen and politicians of the German government.

It is still unbelievable to us that Yahoo gave access to all their email accounts to US authorities. This recent publication of years and years of online surveillance shows again how easy it is to monitor everybody - when the data is not being encrypted. This is why Tutanota encrypts all mailboxes by default.

Today is German Unity Day: On October 3rd in 1990, Germany became one. At the same time it became a truly democratic country. The oppressive system of the German Democratic Republic (GDR) was ended and with it an immense surveillance apparatus disappeared. This is an extremely joyful moment to all Germans, yet, it also has to remind us that we can't take the freedoms we currently enjoy for granted.

Last Sunday Swiss people voted in favour of a surveillance law which will enable Swiss intelligence agencies to tap phones and snoop on email. 65,5% of the Swiss voted in favour of it. This is the first direct vote in favour of more surveillance in Europe. Does that mean the majority of us wants to be monitored?

Last week we were notified by Kevin Froman that your secure mailbox was not safe from the "Target Blank" vulnerability. We fixed this severe vulnerability immediately so that it cannot be exploited.

This week we are celebrating our first Premium release one year ago. The low price for Premium of only 1 Euro per month immediately led to thousands of users upgrading, simply because they wanted to support our privacy-focused email service.

Democracies have created powerful surveillance structures, similar to the ones already being used by current despots. Out of fear from terrorists democratically elected governments around the world have limited everybody's basic rights as citizens. Future authoritarian politicians will use this power against their own enemies: journalists, the opposition, human rights activists, and many, many more.

We are happy to announce that we plan to release a completely new client! We are currently improving your secure email service from scratch, which will greatly improve speed and design.

The Islamic terror has reached Europe, and the only weapon we have against it is an ever increasing surveillance of the general public. At least that’s what Politicians want us to believe. But it is wrong.

Tutanota and Qabel share one goal: Every piece of data has to be encrypted. By developing software that automatically encrypts all data end-to-end, we want to achieve that encryption becomes mainstream. This will enable us to put an end to the illegal mass surveillance online.

All Tutanota users - Premium or Free - can get five additional aliases with today's edition of the German magazine Computer Bild. Soon we will also release alias packages so that everybody can add as many aliases as necessary.

Two years after our first beta release of Tutanota, we have now reached one million users! This is big step for online security because Tutanota automatically encrypts emails end-to-end. Already every second email sent with Tutanota is end-to-end encrypted. This makes illegal mass surveillance of Tutanota mailboxes impossible.

We are happy to release Tutanota version 2.9 (desktop only, mobile apps will be updated later). This release includes multi selection for desktop and some bug fixes.

More than four years ago we started building Tutanota. The challenge we were faced with was automatising the key exchange so that every user can encrypt their emails without any hassle. But at the same time we had to make sure that we don't have access to the private keys of our users.

We are happy to announce the release of a draft feature to your Tutanota mailbox. This is great new feature which will improve the usability of Tutanota a lot. Many more features will follow this year!

As several of you have noticed, we have a new addition to our Support Team: Meike. We are very happy to welcome Meike and to have her on board here at Tutanota! Most of your questions to us will be answered by her while technical requests are mainly handled by one of our developers.

At Tutanota we are building the fully encrypted communication platform of the future. With our open source project Tutanota we aim at making the web open, secure and accessible for everyone. Now we want you to join our team!

This week the German company Vodafone started an encrypted email service for businesses called 'Secure Email'. We welcome their contribution in making our communication as a whole more secure. It is always good to have competition so that we work even harder in making Tutanota the easiest and most secure email service available to everybody!

Four years ago we have started our open source project as entrepreneurs at Leibniz University Hanover. Even back then - two years before the Snowden revelations - we were appalled by the common use of surveillance techniques to which email was and is very exposed. We wanted to build the easiest and most secure email service to stop the snooping on all citizens.

Tuesday (24-11-15) night - starting at 10 pm CET - there is a planned maintenance of our servers. This might lead to short downtimes of Tutanota until Wednesday (25-11-15) morning 6 am CET.

Switzerland plans to revise their data retention law BÜPF so that all communication data (post, email, phone, text messages, ip addresses) can be stored for 12 months. The opponents of this law even say that it would allow the monitoring of mobile phones and the installation of trojans on computers, tablets and mobile phones.

We are happy to release Tutanota 2.3.1. This release just contains a couple of bug fixes.

We are happy to release Tutanota 2.3. You will now find a spam folder in your inbox. This enable us to toughen the spam protection because we don't block spam at the server anymore, thus, giving you full control.

Today 404 German politicians have passed a data retention law making Germany yet another one in the long list of countries introducing data retention to 'fight terrorism'. Only 25 years after the end of the German surveillance state GDR, this law once again puts all German citizens under heavy surveillance.

The recent ruling by the European Court of Justice that declared the safe harbor agreement between the US and the EU as invalid was a great victory for data protection. After the Snowden leaks it became clear that data stored in the US was not safe from surveillance that would be illegal in Europe.

Many NPOs fight political, humanitarian or social causes for the betterment of our global societies. We want to support these organizations. All NPOs can get the secure email service Tutanota Premium with a reduction of 50%, so for only 6 Euro per year.

One of our aims at Tutanota is to fight mass surveillance. End-to-end encrypted emails are important to reach this goal. About 37% of all emails sent from Tutanota are already end-to-end encrypted.

Tutanota is an open source webmail client available in more than 30 languages already. We want everybody to be able to use Tutanota in the easiest way. Join in and translate Tutanota so we can add your language!

We were rather shocked when we heard about the upcoming Lavaboom shut-down next week. The Lavaboom team was building an encrypted webmail service similar to Tutanota, which seemed very promising. We express our sympathy for Lavaboom and wish their team all the best for the future.

Everybody wants your data. Not just the NSA. Google, Facebook, your phone provider, even your torch app and your local store. Yet, we have to share messages all the time with friends and colleagues, with family and civil services. The only chance we have that this information is not monitored by default is end-to-end encryption.

We are excited to finally release Tutanota Premium. Upgrade your account to Premium for only 1 Euro per month immediately and claim a 5 GB extension of your account at no additional cost. This special offer will expire in two weeks.

We've partnered with Golden Frog to enhance your security online. Golden Frog is offering all our users an exclusive special for VyprVPN with 1 GB for free.

We have limited the number of emails that you can send each day to 100. While this is enough for most of our users, unfortunately some have started misusing Tutanota for sending out spam.

We have to apologize that with our last update of Tutanota we missed a bug where some emails could not be opened or deleted. This has been fixed now.

Our open source Android and iOS apps make end-to-end encrypted on mobile incredibly easy. For a maximum of privacy, you can get the Android app directly from our website so that you do not depend on Google services.

We are happy to let you know that Tutanota 1.9.3 is ready! Now with spam protection and preventing of image loading for a better protection of your privacy.

Everybody has the right to whisper. We want that everybody has the right to whisper online as well. That's why your Tutanota encrypted emails can also be accessed via the Tor browser.

After one year of beta testing we are now ready to strip off the diapers! Today Tutanota is leaving its beta phase with the release of brand-new domains: tutanota.com, tuta.io, tutamail.com and keemail.me. Now you can add one free alias to your account.

Following our Android app release in December, we are happy to present the official Tutanota iOS app!

Tutanota uses DANE (DNS-based Authentification of Named Entities). This technology binds the SSL key information to a domain name (DNS) and protects that binding with DNSSEC. DANE makes Man-in-the-Middle attacks practically impossible.
