Hi! The difference becomes clear once you’re dealing with sensitive documents. Email can be intercepted or rejected for legal reasons, while secure platforms — and yes, even online fax — provide encrypted delivery and official confirmation. We once had a contract dispute where the fax receipt was the only proof accepted. That experience convinced me fax still has a place in modern business, especially when security and compliance can’t be compromised.
