Designers have developed the Mailfence logo, which symbolizes a close connection and reliable protection. Communication in the sense that email allows people to communicate. And the protection lies in the technologies used to preserve sensitive data.
Mailfence traces its roots to ContactOffice Group SA, founded in Brussels in 1999 by Patrick De Schutter and Arnaud Juret. The company first developed ContactOffice, a cloud collaboration platform for universities and large organizations across Europe. It combined email, calendars, contact management, documents, and shared work tools long before privacy-focused mail services became a visible market.
By 2007, ContactOffice had passed 350,000 registered users. The company operated without venture capital and kept control over its product direction. Its corporate and academic clients gave it a stable base. At the same time, its servers, protocols, and code later became the technical foundation for Mailfence.
The major shift came in 2013, after Edward Snowden’s revelations about NSA surveillance programs, including PRISM. Reports on data access from Microsoft, Google, Yahoo, and other large providers changed the context of online communication. For a Belgian company with long experience in business communications, privacy became a product issue rather than a side feature.
Mailfence was developed in mid-2013 and officially launched in November 2013 as part of ContactOffice Group. It leveraged the parent company’s existing infrastructure. It added privacy features such as two-factor authentication, encrypted connections, and a transparent data policy. Under Belgian law, user data requests had to be submitted to a local court.
In March 2016, Mailfence released a public beta of OpenPGP end-to-end encryption with digital signatures. In 2020, it reported that Russian mail providers blocked SMTP after it refused Roskomnadzor’s request for user data. In January 2021, Mailfence launched a progressive web app and offered email, calendar, contacts, document storage, group workspaces, and XMPP messaging as an alternative to Microsoft 365 and Google Workspace in Europe.
Meaning and History
ContactOffice began developing mail in 2013, and three years later, a public version was presented. The mail client includes paid and free services. The program code is open for inspection to ensure the absence of built-in tracking systems. All servers are located in Belgium, where privacy laws apply.
The visual sign was initially chosen correctly and conveyed the essence of the company’s offer. Therefore, the only update addressed the details.
What is Mailfence?
A Belgian email client with a particular concern for user privacy. Available since 2016. Works in 12 languages.
Old
The logo consists of the mail service’s name and an image of an envelope. The idea of maximum protection is conveyed in several details:
- In the name. The translation of the word “Mailfence” is “mail fence.” Letters on this service are behind the “high fence.” It protects all site users and prevents attackers from accessing mailbox contents. The service protects against the collection of information; advertising does not study the client’s preferences, and it excludes government agency intervention. In Belgium, where the system’s power is located, government programs that collect information without users’ permission are prohibited.
- In the image of the envelope. On its reverse side, the sealing triangle that seals the letter forms a double helix, intertwining with the bottom of the envelope. This creates a feeling of maximum closure and a strong, thick wire that blocks access to correspondence. The helix indicates an end-to-end encryption system with block asymmetric key encryption (E2EE and AES-256). This is a double layer of protection in which not only emails but also private keys are encrypted. Access to encrypted keys is closed with a passphrase. Key exchange occurs only between the sender and the recipient. Such a system is used for national security and online banking.
The blue color of the envelope represents calmness. Clients can be calm about sensitive data.
Rounded corners are a sign of friendliness and harmony. To protect customers, the service does not sacrifice their convenience and freedom. Users are not overloaded with complex access systems; working with the mail client is easy and convenient.
New
In the new logo, the accents have been slightly shifted. The letters of the name have become lower but more powerful. This emphasizes the meaning of the word. The bold font gives the impression of a wall, a powerful fence protecting the server. The letters are grouped, and the level of protection has increased.
The envelope also became larger. It is twice as high as the capital letter of the title. This emphasizes the importance of user emails. Customers’ interests are at the forefront of the company’s priorities.
The double helix has remained unchanged, but the envelope’s color is now lighter blue. It resembles the transparency of the heavenly heights. The company provides users with special reports detailing which requests and user data the system received. Thanks to this, customers can know who was interested in their data and whether the system rejected the request.
Font and Colors
The logo combines shades of blue, black, and white.
- The choice of cold blue shades is not accidental. They convey neutrality, indifference, and business relations. The colors indicate that the server owners are neither overly curious nor interested in the contents of the envelopes. For them, letters, once sent “to one person,” are only packages that need to be delivered to recipients. The service does not have primary keys that allow you to “bypass” encryption and secretly read user messages. The password is not sent to the server; it is stored on the client’s computer. Changing the new logo’s color to a lighter one resembles a dissolution. Mailfence has a feature that limits the lifespan of messages, after which they are automatically deleted.
- Black is the color of reliability, confidence, and closeness.
- The white color of the closing wire shows that every new letter is protected with maximum security. White symbolizes honesty, transparent terms of use, and protection from fraud. The service base is not for sale. It protects users from their own and other people’s mailing lists to which the client did not subscribe.
The logo uses a harmonious geometric font, Typold Bold, presented by The Northern Block.
