Frequently Asked Questions
Can I send a fax from Gmail for free?
Gmail does not have a built-in fax feature. You need a third-party email-to-fax service like mFax.to. Most services offer a free trial or pay-per-fax pricing so you can send your first fax without a subscription.
What email format do I use to send a fax?
Compose a new email and enter the fax number followed by the service domain in the To field — for example, [email protected]. Attach your document as a PDF and click Send.
Is faxing from email HIPAA compliant?
It can be — if your email-to-fax provider uses TLS encryption and signs a Business Associate Agreement (BAA). mFax.to supports HIPAA-compliant faxing. See our [HIPAA compliant fax guide](/blog/hipaa-compliant-fax/) for details.
What file formats can I fax via email?
PDF is the gold standard. Most services also accept DOCX, XLSX, JPG, PNG, GIF, and TIFF. Avoid password-protected files — the fax gateway cannot open them.
Do I get a confirmation when the fax is delivered?
Yes. After the recipient's fax machine confirms receipt, you receive a delivery confirmation email with a timestamp and page count — similar to a read receipt.
