mailbox Year in Review 2025: Secure communication needs a firm stance

Thu, 18 Dec 2025 00:00:00 +0100

As the year draws to a close, it is clear how much the framework conditions for digital communication and collaboration have changed. Security, data protection and political influencing factors have not remained abstract in 2025, but have become part of everyday life for companies, public authorities and private users. With this in mind, it is worth taking a look back at the developments that have characterised this year – and which show why reliable email communication and secure digital collaboration matter more than ever today.

mailbox becomes a secure digital workplace

These changing requirements are also reflected in the further development of mailbox. With the development towards an integrated, digitally sovereign workplace, a central step has been taken. Email, calendar, contacts, cloud storage and collaboration are growing closer together – with the aim of enabling secure communication and productive work in a trustworthy environment. The focus was on clarity, control over data and the deliberate reduction of external dependencies.

Political developments worldwide and the call for European alternatives

The fact that technological decisions cannot be viewed in isolation from political developments became particularly clear in 2025. The political change of course in the USA has once again made many organisations aware of how quickly legal and regulatory frameworks can change. Against this backdrop, many users scrutinised existing dependencies. Many made a conscious and forward-looking decision to switch to European alternatives.

BSI Gold status and transparency about data localisation

In such an environment, verifiable security standards and transparent origins are becoming increasingly important. An important signal of this was the award of mailbox with the Gold status of the German Federal Office for Information Security (BSI). Complemented by renowned quality seals for German software and hosting, this underlines our commitment to combining the highest security requirements with clear legal positioning – a decisive factor for many organisations when choosing their digital infrastructure.

Chat control and the question of digital self-determination

Parallel to this, fundamental questions of digital self-determination came back into focus in 2025. The political debate surrounding chat control in 2025 made it clear how fragile the right to confidential communication remains. The attempt to weaken encryption through technical backdoors calls into question the basic principles of data protection and IT security. mailbox has taken a clear stance in this discussion: Security is not divisible – and digital independence requires that communication can remain confidential.

As the year draws to a close

All these developments show how closely technology, politics and social responsibility are now interlinked. We would like to thank all our customers, partners and supporters for their trust and open dialogue during this eventful year. We wish you a relaxing holiday season and a happy new year. May 2026 be characterised by decisions in the spirit of digital sovereignty, secure communication and the responsible use of digital technologies.

Open letter: mailbox against chat control

Tue, 07 Oct 2025 00:00:00 +0200

Time is running out. On 14 October 2025, the EU Council will vote on the CSA Regulation, commonly known as chat control – legislation that could fundamentally change digital privacy for 450 million Europeans. The Danish Council Presidency is pushing for a vote, and Germany sits at the centre of it all. Germany's position could determine the regulation's fate, but the federal government's once-clear rejection appears to be wavering.

mailbox: Relaunch creates the digitally sovereign workplace

Tue, 09 Sep 2025 00:00:00 +0200

Berlin, 9 September 2025 – mailbox.org, Germany's leading provider of secure digital communication, has undergone a comprehensive technical and visual relaunch and is now presenting itself as a holistic, digitally sovereign workplace. The trusted secure email service has evolved under the streamlined name "mailbox" into an integrated platform that unifies all aspects of modern workplace communication while maintaining European data protection standards and digital sovereignty.

Technical foundation rebuilt from the ground up

The new mailbox Suite brings together email, calendar, contacts, office tools, video conferencing and cloud storage in a single, intuitive solution – fully GDPR-compliant and running exclusively from German data centres.

"With mailbox, we've reimagined the digital workplace: independent, secure and intuitive. Our customers can communicate with complete autonomy and stay productive – whether they're in the office or working on mobile through their browser," says Balint Gyemant, Chief Product Officer at mailbox. "We're proud to have delivered a real breakthrough for our users that brings together digital sovereignty with state-of-the-art technology."

Intuitive design meets mobile flexibility

The technical relaunch features a completely refreshed user interface with enhanced dark mode, customisable themes and streamlined workflows. Smart keyboard shortcuts, seamless integration across all communication channels, and a new Progressive Web App (PWA) for mobile working round out the package – delivering an app-like experience directly in the browser.

Intelligent email features for better control

The email functionality now includes modern features like "undo send", email categories and enhanced reply options. Customisable read receipts let users control how quickly emails are automatically marked as read. Attachments from recent emails can be inserted straight into new messages, while adjustable font sizes and configurable labels allow for personal customisation.

Calendar and online meetings work in perfect harmony

The newly branded mailbox Office brings together calendar, contacts, document editing, surveys and chat in one integrated solution. Direct integration with mailbox Meet automatically links video conferences to calendar appointments: meeting links are generated automatically with calendar entries. A countdown alerts users to upcoming meetings, while optional participant flags enable flexible meeting planning. Mobile users get a dynamic week view, and the year view now works seamlessly across all devices.

New brand, unchanged commitment

Alongside the technical advances, mailbox has unveiled a completely refreshed brand identity. The move from "mailbox.org" to simply "mailbox" and the new product names – Mail, Office, Meet and Drive – that make up the mailbox Suite reflect a focus on clarity and ease of use.

This strategic shift maintains the company's core commitment to security and data protection. mailbox continues to reject advertising, tracking and data monetisation while ensuring full GDPR compliance and legal certainty.

"Our repositioning demonstrates that European technology doesn't just match the competition – it shows that data protection and transparency are genuine quality differentiators," says Peer Heinlein, CEO of the Heinlein Group, mailbox's parent company.

European alternative with German engineering standards

The timing couldn't be better: demand for European alternatives continues to surge. mailbox offers a key advantage over US services by remaining outside the scope of the US CLOUD Act. For businesses and public sector organisations, this means legal certainty through data processing and storage exclusively in Germany – perfect for compliance-sensitive applications.

"What people once dismissed as niche thinking has turned out to be ahead of its time," Heinlein adds. "I'm incredibly proud that mailbox represents the digital sovereignty our customers genuinely need."

Digital independence as core strategy

The mailbox relaunch aligns with the broader Heinlein Group strategy, which has championed security, data protection and digital independence for over 30 years, delivering comprehensive German-made alternatives through the Heinlein Support, mailbox, OpenTalk and OpenCloud brands.

With its complete technical redesign across all components, mailbox is setting new benchmarks for digitally sovereign workplaces in the European market. The new mailbox Suite is available immediately for new customers, with existing accounts being migrated gradually.

Tue, 09 Sep 2025 00:00:00 +0200

From mailbox.org to mailbox – and this is just the beginning. Along with the name change, we've completely redesigned our entire product, both technically and visually. All components have been rebuilt from the ground up and now form an integrated platform that covers every aspect of digital communication. Alongside a completely new brand identity, this strategic transformation combines technical innovation with consistent brand development. We're setting new standards for modern work and secure communication for businesses, the public sector and private individuals.

BSI gold status for mailbox

Fri, 22 Aug 2025 00:00:00 +0200

Great news for anyone who values secure email communication: mailbox.org has been awarded gold status in the 2025 Email Security Year by Germany's Federal Office for Information Security (BSI)!

What does this mean for you?

This gold status officially confirms our position as an industry leader in Germany. We haven't just committed to implementing the latest email security standards – we've been successfully using them for years.

Maximum security through DNSSEC and more

To achieve gold status, we've met BSI's strictest requirements, particularly through full implementation of DNSSEC (Domain Name System Security Extensions). This technology protects you from DNS attacks and ensures your emails genuinely come from the stated servers.

We also use all other security protocols recommended by BSI:

DMARC and DKIM for authentication
DANE for additional encryption
SPF to prevent email spoofing
TLS for secure transmission
MTA-STS for secure server connections

Your protection from cybercriminals

What does this mean in practice? Fraudsters find it much harder to send fake emails in your name or trick you with phishing attacks. All your emails are transmitted with encryption, so nobody can read or tamper with them during transit. Your digital identity receives the best possible protection with us.

A shared effort for better security

Email Security Year 2025 is a joint initiative by BSI, eco and bitkom with a clear goal: to make email communication in Germany measurably more secure. We're delighted to be part of this important initiative and to lead by example.

As Peer Heinlein, founder and CEO of Heinlein Group, puts it: "We've been implementing these security standards at mailbox.org as a matter of course for many years. Our customers can rely on us to protect their digital identity reliably."

Transparency through the new email checker

You can now easily check your email provider's security standards: BSI has developed a new email checker that transparently shows which security measures your provider implements.

Why we do this

At mailbox.org, your digital sovereignty and data protection have been central to everything we do since our founding in 2014. This award confirms what we've long believed: security isn't optional – it's a fundamental right. And you can continue to rely on that.

Email security: mailbox.org achieves gold status

Fri, 22 Aug 2025 00:00:00 +0200

Berlin, 22 August 2025 – Secure email provider mailbox.org has become one of the first companies to achieve gold status in the Federal Office for Information Security's (BSI) Email Security Year 2025 and thus made it into the “Hall of Fame of e-mail security”. The company, part of the Heinlein Group which champions digital sovereignty, data protection and open source, is now among industry leaders. mailbox.org has committed to fully implementing the latest email security standards and has already successfully put them into practice.

mailbox Suite: New design and smart features

Mon, 19 May 2025 00:00:00 +0200

Exciting news for all participants of the mailbox beta program! Starting today, as a beta tester, you can experience the new mailbox Suite.

BÜPF Revision: The Swiss Surveillance Law

Tue, 13 May 2025 00:00:00 +0200

The Swiss government intends to toughen its surveillance law. With the revision of the BÜPF (Federal Act on the Surveillance of Post and Telecommunications), potentially far-reaching changes are on the horizon that could affect the data protection of millions of users. The supposedly safe haven for digital privacy is crumbling: in future, Swiss email providers with more than 5,000 users may be required to deliver metadata to authorities in real time. This would particularly affect those Swiss services that have until now advertised strict data protection.

The BÜPF and the planned revision: The digital overhaul

Since 2002, Switzerland's surveillance law has regulated the circumstances under which authorities may access communication data. However, the partial revision of the associated ordinances (VÜPF and VD-ÜPF) now sought by the Federal Council goes far beyond a mere update. Whilst official bodies present the changes as necessary adaptations to 5G technology, the draft contains measures that would significantly increase the level of state surveillance.

Digital X-ray: How deep the new surveillance would reach

The planned changes to the BÜPF would deeply encroach on digital privacy and would also affect users of Swiss email services. It is crucial for users to understand what authorities might see in the future and what they would not.

Future surveillance would encompass significantly more metadata, including IP addresses, recipient data and location information – data that is just as sensitive as content, as it can reveal movement and relationship profiles. Authorities would thus gain systematic access to information about who communicates with whom, when this happens and from which location. This metadata would be collected in real time and transmitted to authorities. For Swiss email services that have so far not stored IP addresses as standard, such data protection-friendly practices would no longer be possible. Last but not least, the processing deadlines for requests are to be shortened – from one working day to six hours for large providers and from two working days to one for smaller services.

End-to-end encryption through PGP remains untouched, meaning Swiss providers would still not be required to decrypt encrypted content. Anyone who consistently encrypts their emails with PGP would therefore continue to protect the content of their communications even after the potential legislative change.

What happens after the end of the consultation?

The deadline for the consultation – a Swiss procedure in which cantons, parties, associations and affected organisations could comment on the draft – expired on 6 May 2025. According to reports, this consultation is said to have met with widespread rejection. The Federal Department of Justice and Police (FDJP) is now evaluating the submitted statements and revising the draft if necessary. This process can take several months.

The Federal Council will decide on the final version no earlier than autumn 2025. If approved, the new regulations could come into force from 2026, although massive resistance from businesses and data protection organisations could delay the process or lead to substantial changes.

The great exodus has begun

In response to the impending regulations, leading providers have already begun relocating their servers abroad – primarily to Germany and Scandinavian countries. Some companies are even considering moving their headquarters completely out of Switzerland. This development shows how seriously the industry is taking the planned changes. Leading industry representatives particularly criticise that the planned measures would go far beyond the regulations in Germany and the EU.

Data protection in international comparison

Whilst Switzerland has long been known for its high standards in digital privacy, Germany now offers significantly stronger protection in some areas. Since 1997, Switzerland has permitted blanket, non-targeted data retention for six months, which would be extended to continuous real-time surveillance with the planned BÜPF revision. In Germany, on the other hand, the Federal Constitutional Court has repeatedly declared such blanket data retention unconstitutional. Here, surveillance measures generally require a judicial order and specific suspicion – basic principles that could potentially be diluted with the Swiss law revision.

Checklist: What users should check now

If you currently use a Swiss email service, you should check the following aspects in light of the possible legislative changes:

Encryption level of your emails: Is only transport encryption activated, or do you use end-to-end encryption like PGP?
Metadata protection: What metadata does your provider store, and how will they handle the potential real-time surveillance obligation?
Server locations: Has your provider already relocated servers abroad? If so, which law applies to your data stored there?
Future plans of the provider: Are there official statements on possible relocations or adjustments to data protection policies?
Examine alternatives: Consider switching to a German provider like mailbox.org, which is protected by strict constitutional court rulings and the GDPR.

Outlook: The price of security

The planned revision of Swiss surveillance law marks a turning point. What was once considered a data protection paradise is increasingly developing into a surveillance state that recalibrates the balance between security and privacy – and, in the view of many experts, goes too far. The threatened exodus of email providers is a wake-up call – not just for Switzerland, but for everyone who values digital fundamental rights. The debate shows once again that data protection is not a given, but a fragile asset that requires constant vigilance.

Microsoft price increase 2025: A wake-up call

Mon, 28 Apr 2025 00:00:00 +0200

As of 1 April 2025 at the latest, a comprehensive price increase for nearly all Microsoft services has come into effect. This affects both business and private customers and has been gradually implemented since December 2024. These price increases come at a particularly inopportune moment for many companies, given the current inflation and general fears of recession. They represent not only a financial burden but also raise fundamental questions about long-term strategy and dependencies in the area of digital infrastructure.

Affected products and specific increases

Microsoft's price adjustments affect almost their entire cloud portfolio, including Microsoft 365, Office 365 subscriptions, Windows 365, Power BI Pro and Premium-per-User, as well as Teams Phone. Some price increases are particularly dramatic: Teams Phone will be 25% more expensive (from $8 to $10 per user), whilst Power BI Pro will increase by as much as 40% (from $10 to $14). For Windows Server and System Center, increases of 10% have been announced.

The new billing model: Additional costs through monthly payments

In addition to these direct price increases, Microsoft has introduced a new billing model where annual subscriptions with monthly payment will be 5% more expensive than annual advance payments. This seemingly small adjustment means a significant cost increase for companies with numerous licences and aims to encourage customers to pay in advance.

Strategies behind the price adjustment

Microsoft justifies the price increases with the "increased value" of their products through continuous innovation, particularly in the field of artificial intelligence – such as with Copilot – as well as with higher development costs. However, the adjustment of the billing models also serves to steer customers towards annual contracts with advance payment. This improves Microsoft's cash flow and binds customers in the longer term – a classic example of vendor lock-in strategies.

Options for affected companies

Companies affected by the price increases have a special right of termination at the time the changes take effect. However, upon termination, the contract does not end immediately but at the end of the respective contract term. Those who do not exercise their special right of termination automatically accept the new prices.

Those who wish to avoid vendor lock-in and want to strategically realign should take the following measures:

Analyse licence inventory: Which Microsoft products are actually being used and to what extent? Are there unused or oversized licences?
Review payment model: Consider switching from monthly to annual payment to avoid the 5% price surcharge, if it's too late to cancel
Evaluate alternatives: Are there more cost-effective alternatives that offer the needed functions?
Strategic realignment: Align long-term IT strategy towards independence, data protection and cost control
Examine hybrid solutions: Does the entire company need to use Microsoft products, or can some areas already be switched to alternatives?

mailbox.org as a data protection-compliant alternative

For companies wishing to become independent from US providers, mailbox.org offers a secure, privacy-friendly alternative. mailbox.org impresses with PGP-encrypted emails, calendar, contacts, task management and browser-based office applications. A decisive advantage lies in the exclusive data storage in Germany, complying with the strictest data protection regulations.

The solution is characterised by a transparent pricing model without hidden costs and offers a balanced relationship between functionality and costs, especially for small and medium-sized enterprises. With its focus on security, data protection and European values, mailbox.org positions itself as a future-proof alternative in the changing digital landscape.

Impact for private users

For private users, mailbox.org also offers an attractive alternative with tariffs starting from €1 per month, as they too are affected by the price increases. Microsoft 365 Family prices will rise from €99 to €129 (+30%) and Personal from €69 to €99 (+43%). It's worth noting that the advertised AI functions such as Copilot are subject to significant limitations and are only available to the main account user.

Digital sovereignty as a future perspective

The current price increases highlight the problem of comprehensive dependence on non-European tech giants. Forward-thinking companies now have the opportunity to reconsider their digital infrastructure and switch to European solutions. This is more than a price issue – it's an investment in digital sovereignty, data security and entrepreneurial independence in an increasingly data-sensitive business world.
