Despite the dominance of email, social media, and instant messaging platforms, fax marketing remains surprisingly resilient in 2025—especially in specific industries where security, compliance, and traditional communication still reign. These sectors often have deeply ingrained workflows, regulatory requirements, or communication habits that make fax lists an effective outreach channel.
1. Healthcare and Medical Services
Hospitals, private practices, clinics, and fax lists medical suppliers still rely heavily on faxing due to HIPAA compliance, strict patient data regulations, and outdated but reliable infrastructure. Many electronic health record (EHR) systems are still integrated with fax for transmitting referrals, prescriptions, and insurance forms. For marketers, this means fax remains one of the few compliant outreach channels available in healthcare.
2. Legal and Financial Services
Law firms, accounting practices, and financial consultants continue to use fax for secure document transmission. Courts and government agencies often require or accept faxes as formal documentation. This makes these sectors particularly responsive to well-targeted fax communications, especially for B2B services, professional tools, or niche offerings such as litigation support or legal tech products.
3. Government and Public Sector
Fax usage persists in many government offices—local, state, and federal—due to legacy systems and concerns around cybersecurity. Fax is still viewed as a secure and dependable form of communication, especially in procurement departments and regulatory agencies. For businesses selling to the public sector or engaging in government contracting, fax marketing can be a direct path to key decision-makers.
Bonus: Real Estate & Franchising
Many real estate investors, brokerages, and franchise development groups use fax for document-heavy transactions and outreach. In these fast-moving industries, fax remains a tool for transmitting forms, offers, or urgent updates without reliance on email open rates.
Bottom Line: In 2025, fax lists remain highly relevant in industries where trust, regulation, and established processes outweigh the push toward digital-only communication. For B2B marketers targeting these sectors, fax marketing—when done correctly and compliantly—is still a viable and effective channel.
