How do I send a virtual fax?

    Send faxes through email, removing the need to have a physical fax machine and allowing you to fax on the go. Not available in Brazil and Mexico.

    1. From your email account, compose a new message.
    2. Enter faxNumber@‹domain› in the To: field.
      • Replace faxNumber with the external 10 digit fax phone number, without the 1 or any dashes (e.g., 8012321987). You cannot send a virtual fax to an internal extension or a number that requires an extension (e.g., 8012321987 ext 1121).
      • Replace ‹domain› with your unique domain. PBX Administration (classic) users will find their domain in the parentheses at the top of their portal dashboard. GoTo Admin portal users will find their domain in Account Settings.
      • We are now GoTo and the address has been updated. However, faxNumber@‹domain› is still supported.
      • You can now send virtual faxes to multiple recipients. You can add recipients to the To, CC, and BCC fields.
    3. Enter the virtual fax machine’s access code in the Subject: field. If you add a subject, enter a space after the access code and then include the subject (e.g., 294034210 March Invoice).
      Note: If you do not have the virtual fax machine’s access code, contact your admin for assistance.
    4. Remove all text from the body of the email, including email signatures.
    5. Attach file(s) to the email. If including a cover sheet, attach that first. Supported file types:
      File Type File Format
      Microsoft Office .doc, .docx, .ppt, .pptx, .xls, .xlsx
      Document .pdf, .rtf, .txt
      Image .jpg, .tiff, .png, .bmp, .gif
      Note: Larger files may experience lag time or potentially fail. We recommend no more than 200 pages at a time.
    6. Select Send.
    Results: If the fax was delivered successfully, you may or may not receive an email confirmation as this functionally must be enabled by your admin. Emails are always sent in the case of transmission failures. Email communications will be sent from, or Please ensure these domains are allowed so that emails are not automatically filtered as spam.
