Frequently Asked Questions
What is fax broadcasting?
Fax broadcasting (also called a fax blast or mass faxing) is the process of sending a single fax document to a large list of recipients simultaneously. A cloud fax platform handles all dialing, transmission, retries, and delivery confirmation automatically.
Is fax broadcasting legal?
Yes, with restrictions. The TCPA and Junk Fax Prevention Act govern advertising faxes. You need either an established business relationship with each recipient or their prior express consent. Transactional faxes (invoices, receipts, policy documents) are exempt. See our [junk fax and spam guide](/blog/junk-fax-spam/) for the full rules.
How much does fax broadcasting cost?
Per-page rates in the US typically run $0.01–$0.03 per page. A 2-page broadcast to 1,000 recipients costs roughly $20–$60. Monthly subscription plans with included pages are available starting around $20/month.
What is the difference between fax broadcasting and email marketing?
Fax broadcasting reaches recipients through the telephone network, bypasses email spam filters entirely, and achieves open rates above 90% compared to email's average of roughly 22%. Fax also provides legally recognized per-recipient delivery confirmation, which email cannot reliably offer.
Do I need consent to send a broadcast fax?
For advertising faxes: yes. You need either an established business relationship or prior written consent. Every advertising fax must also include a clear opt-out notice on the first page. Transactional faxes (invoices, receipts, compliance documents) do not require consent.
