mFax – Faxing via Email

Addressing the Email

Addressing the email

Using any mail client such as Outlook or Gmail, compose a message addressed to an 11 digit [email protected]

It is important to always include the full 11 digits for faxing any number in the US or Canada. 

Including a Cover Page

If you have your cover page setting turned on, mFax will automatically take details from your email and populate it directly onto a cover page. Email subject line will populate RE: field of the cover page and the body of email will populate the Comments field of the cover page. (see screenshot below)

Email with cover page

You will notice that the To: field on the cover page is populated with the destination fax number by default. To populate the name of a person/business instead of the fax number simply format as follows:

Fax Cover Letter


When sending a fax from email you can attach multiple documents types (see below). You can attach a single document or multiple documents (varying formats is fine) and they will be rendered, converted to a faxable format, and sent to your destination fax number. Once your documents are attached, simply hit SEND. That’s it! We’ll take care of the rest.

Allowed Email Attachments

  • Image Files (TIFF, GIF, PNG, JPEG)
  •  Adobe Acrobat Files (PDF)
  •  Microsoft Office Files (DOC, DOCX, XLSX, PPTX)
  •  Printer File Formats (PCL, EPS, PS)
  •  Text Files (TXT, RTF)

TIP: If you create a file using a scanner or print to file, always choose the option of black and white for the output.
