What Fax.de does
Fax.de, operated by comfax GmbH and headquartered in Seevetal-Ramelsloh, Germany, is a cloud-based virtual fax, SMS, and postal letter service provider that has operated continuously since 1996. The platform enables individuals and organizations to send and receive faxes, SMS messages, and physical letters (Postbrief) without owning dedicated hardware, accessible via Windows software (Easy-Office, Easy-Broadcast), a browser-based Online-Kundencenter, and dedicated iOS/Android mobile apps including a free FreeFax/FAX-it! app offering one free page per day to 50 countries. The underlying infrastructure is a German high-performance data center with 24/7 monitoring and direct fiber connectivity to major telephone providers globally, supporting both consumer/SMB self-serve usage and enterprise deployments via the Fax Cloud virtual fax server for organizations with thousands of workstations, particularly those migrating from ISDN to VoIP.
The company's monetization combines prepaid send packages (Basic at EUR 12), monthly subscriptions with a local fax reception number (Light at EUR 5.95/month), and annual low-volume subscriptions (Fine at EUR 35.70/year), with additional in-app page packages for mobile users. Distribution is primarily product-led through online registration, free trial sends, and app store presence (approximately 10 million cumulative app downloads and 5+ million installed users historically), supplemented by enterprise field sales for large deployments. The firm also offers developer APIs (XETF email-to-fax and XML-SOAP real-time interface) and integrations with Dropbox, Google Drive, OneDrive, and Box.
