Why do some clients refuse to use email for sensitive docs?

A client recently asked me not to send their financial documents via email—even with password protection. They insisted on using fax. It made me wonder: is email really that insecure compared to digital fax?

It seems excessive at first, but once I read up on it via ask4research.info I understood their concern. Email, even when encrypted, passes through multiple servers and can be vulnerable to interception, phishing, or misdelivery. Password-protected attachments aren’t foolproof either. Digital fax, by contrast, uses secure, direct transmission with end-to-end encryption and doesn’t store files on shared servers. Plus, it provides automatic delivery confirmation, ensuring documents arrive exactly where intended. That’s why cautious clients still trust it—it's designed specifically for secure document handling and regulatory compliance.
