How to Fax by email

Updated on December 5, 2025

Send a Fax by Email #

Use your regular email (Gmail, Outlook, etc.) to send a fax through your PeerOne Cloud PBX service no fax machine required.

PeerOne lets you send faxes directly from your email account. Instead of printing and using a physical fax machine, you simply compose an email and PeerOne converts it into a fax for you.

What You Need #

  • An active PeerOne Cloud PBX account with fax enabled.
  • An email address (e.g., Gmail, Outlook, Apple Mail) configured on your computer or mobile device.
  • The destination fax number you want to send to.

Step 1 – Compose the Fax Email #

  1. Open your email app (for example, Gmail on the web or Outlook on your computer).
  2. In the To field, enter:
    fax@peerone.ca
  3. In the Subject line, enter the destination fax number using this format:
    [out] phone number
    Example: [out] 4165551234
  4. The body of the email can be left blank or used for any notes you want to include with the fax.

Step 2 – Attach the Document(s) #

  1. Attach the file(s) you want to fax (for example, a PDF or document file) to the email.
  2. Double-check that the attachments are complete and legible the fax will be generated from these files.
  3. Review the To address and Subject one more time to confirm the fax number is correct.
Tip: If you frequently fax to the same number, save a draft or template email with the correct format, and just update the attachments each time.

Step 3 – Send the Fax #

  1. Click Send in your email client.
  2. PeerOne receives the email at fax@peerone.ca, converts the attachments into a fax, and sends it to the phone number you specified in the subject line.
  3. Watch your inbox for any confirmation or error messages related to the fax delivery (if configured on your account).

Troubleshooting & Best Practices #

  • Fax did not go through? Verify that the subject line is exactly in the format [out] phone number with a valid fax number.
  • No response or confirmation? Check your spam/junk folder and confirm that your PeerOne fax service is active on your account.
  • Attachments not readable? Use clear, high-contrast documents (PDF is usually best) and avoid photos with very small text.
  • If issues persist, contact PeerOne Support and provide the time you sent the email and the fax number you were trying to reach.
