A fax broadcast sends one document to hundreds or thousands of recipients at once — with 90%+ open rates and per-recipient delivery confirmation. This complete guide covers setup, costs, compliance, and best practices for 2026.
Frequently Asked Questions
What is a fax broadcast?
A fax broadcast (also called a fax blast or mass fax) is the process of sending a single document to multiple fax numbers simultaneously. You upload a file, import a recipient list, and a cloud fax service transmits to all recipients in parallel — with per-recipient delivery confirmation.
How much does a fax broadcast cost?
Per-page rates typically run $0.01–$0.03 per page in the US. A 1-page broadcast to 500 recipients costs $5–$15. A 2-page broadcast to 1,000 recipients costs $20–$60. Monthly subscription plans start around $20–$25/month with included page bundles.
Is fax broadcasting legal?
Yes, within rules. The TCPA and Junk Fax Prevention Act govern advertising faxes. You need either a prior business relationship or documented consent for each recipient. Every advertising fax must include a clear opt-out notice on the first page. Transactional faxes (invoices, compliance documents) are exempt.
What open rate does fax broadcast achieve?
Fax broadcasts consistently achieve open rates above 90%, compared to email's average of roughly 22%. Fax bypasses spam filters entirely — the message either delivers to the physical or virtual machine or it doesn't, with a confirmed receipt either way.
Can I personalize a fax broadcast for each recipient?
Yes. Modern fax broadcast services support mail merge, letting you insert per-recipient fields (name, company, account number) into the document or cover page dynamically. You provide these in your CSV import.
