What is a fax confirmation email?

A fax confirmation email is an automated notification sent by an online fax service after a transmission completes. It confirms whether the fax was successfully delivered and typically includes the recipient's fax number, date and time, number of pages, and a unique transmission ID.

Is a fax confirmation email legally valid proof of delivery?

Yes. Fax confirmation reports — including email confirmations — are recognized as legal proof of transmission in the U.S., with established case law supporting their validity. Unlike email read receipts, which courts have ruled inadmissible as hearsay, fax confirmations carry real legal weight.

Why am I not receiving fax confirmation emails?

The most common causes are: the email landed in your spam folder; the wrong email address is registered in your fax account settings; or your email provider's filters are blocking the fax service's domain. Whitelist your fax service's sending address and check your account notification preferences.

What is the difference between a fax sent and a fax delivered confirmation?

A "sent" confirmation means the data left your system. A "delivered" confirmation means the receiving fax machine acknowledged successful receipt. "Delivered" requires a two-way handshake and is stronger proof. Most modern online fax services provide true delivery confirmation, not just sent status.

How long should I keep fax confirmation emails?

For HIPAA-regulated healthcare organizations, fax audit logs must be retained for a minimum of 6 years. For general business purposes, follow your industry's document retention policy — typically 3 to 7 years for legal and financial records.
