Fax by email

Send a fax by email

On an e-Fax or Corporate Fax line you can fax a document just by emailing it. No upload, no app.

How it works

  1. Sign in, open Fax lines, choose Settings on your line and turn on email sending.
  2. Email your document to the destination fax number at fax.jamfax.com, using digits only. To fax (305) 555-0142, email 13055550142@fax.jamfax.com.
  3. We fax it and reply to your email to say it was sent, or why it wasn't.

What you can send

  • Up to 5 PDF or TIFF attachments, 10 MB each. They are sent as one fax, in the order attached.
  • Send from the email address you sign in to JamFax with. Mail from any other address is ignored, and we check that the email really came from your address before faxing anything.
  • The text of your email is not faxed and there is no cover page, so put anything the recipient should read in the document.
  • Up to 30 faxes by email an hour. Use the browser for more.
  • Pages sent by email count toward your plan's monthly pages like any other fax.

Faxing abroad? International faxing is off until you turn it on, and Jamaica is from $0.60 a page. See international prices. To fax from your own software instead, see the developer API.

Step by step for your mail app: fax from Gmail or fax from Outlook.
