How to email a fax | Fax Authority (2023)

Last Update: August 9th, 2021

There are two ways to email to a fax machine:through an online fax service or an enterprise level fax server.

There are other ways to fax from a computer that uses a connected fax machine or fax software (a direct replacement for a fax machine) however; these approaches do not have the benefit of being able to be managed through email and also require a land-line phone line.


  • There is no “out of the box” way an email program can send a fax. An online fax service, fax server, or connected fax machine is required to enable email to fax and fax to email.
  • You can send and receive a fax with email by using an online fax service, including email services such asGmail, Hotmail, and Outlook.
  • You can send and receive a fax using a connected fax machine or multifunction printer as a relay. Most only have the ability to receive a fax and forward it to email, while sending is done through the print driver.
  • Enterprise & corporate level fax servers can add “email to fax” and “fax to email” capability to an organization.
  • Alternatives include fax software and finding a local establishment to send and receive faxes

How fax to email (and email to fax) works

There are two ways for connecting fax and email. The first is with a fax server (an online fax service is a type of fax server), the second is with a connected fax machine with email capability.

An online fax service is a type of fax server. The main difference between the two is that fax serversare managed directly (typically found in enterprise and corporate environments) while online faxis available as a service.

A connected fax machine is a fax machine that iscontrolled by a computer or smartphone. Many connected fax machines can send a fax from the print driver, and some can relay the fax to an email whenever a fax is received.

How to send and receive a fax to email (or email to fax) with an online fax service or fax server

Email to fax (and fax to email) is a standard function with most online fax services.

Sending an email to fax

Steps vary by service provider. A typical approach to sending an email to fax with an online fax service is:

Step 1 – Prepare a new email. Open a new email as you normally would.

Step 2 – Put the “to” fax number into an email address. To send the email to a fax send to an email address that is the fax number @ For example, if the fax number to send to is +1 (212) 555-5555, and the online fax service is Nextiva, the email to send to is [emailprotected]

Step 3 – Enter subject line and body of the email. The subject line and body of the email will be converted over to the relevant parts of the fax’s cover page. The subject line will be the email’s subject line, the body of the email will be the body of the cover page. Information about the sender automatically inserts into the cover page from the service’s configuration.

Step 4 – attach the documents to fax.More than one document can be attached, and file formats such as Word and PDF are universally compatible.

Step 5 – send the email. The email travels to the fax service. The fax service will then convert the email information over to a fax and call the fax number.

Step 6 – wait for confirmation (or message failure).The fax service sends a confirmation page email showing the fax was successfully sent or not.

Receiving a fax to email

Steps vary with each provider. Here is a typical approach to receiving a fax to an email address:

Step 1 – the fax service waits for the fax line to ring.The fax service is always on regardless of whether your computer, smartphone, or email client is active.

Step 2 – the fax service answers the ringing fax line. The sending fax machine transmits the fax information to the fax service.

Step 3 – the fax service stores the fax.A web browser, software program, or app can access the faxes.

Step 4 – the fax service emails a copy of the faxto the designated email address(es) (some fax services allow for more than one recipient email address). The email arrives with a copy of the fax in PDF format.


The system can work all types of devices, including Computers (Windows, Mac, and Linux) and Smartphones/Tablets (iPhone, Android, Blackberry, and Windows Phone). It can work anywhere that email can be accessed and a PDF document can be displayed.

All types of email addresses are compatible. An online email to fax service can work with:

  • Webmail email addresses such as Gmail, Hotmail, Yahoo! Mail, and Outlook 365 webmail.
  • Verizon, AT&T, Time Warner, Comcast, CenturyLink, and any internet service provider’s email.
  • Any email client such as Outlook, Thunderbird, and Mac Mail.


The limitations of fax to email with an online fax service or fax server come mostly from the storage size the email provider allows. Most email providers allow more than enough room; however fax documents take up much more computer storage space than an equivalent document typed directly into an email.

With a fax server, there may be limitation set by the administrators as to what type of email can send and receive a fax. However, these limitations are specific to the organization and not the server software.

Use a connected fax machine to send and receive a fax with email

Most connected fax machines have the ability to “print” to fax through the print driver. Some connected fax machines (or multifunction printers with fax capability) canforward a fax to email.

A connected fax machine will still require a landline phone line, just like a regular fax machine.

“Printing” to the fax driver

Connected fax machines can send a fax by “printing” the fax.

The specifics vary by fax machine. It is typical to have the ability to load the print driver (go to print the file, select more options). Within the print driver is an option to send the document to a fax number.

Other fax machines have software that runs the functions for sending the fax. Within the software, there is an option to build a simple fax and send it as a fax.

Forward fax to email

Some connected fax machines can forward (or relay) a received fax to an email address. When a fax is received, an email sends to a designated email address with a PDF copy of the fax attached.

Alternatives – fax with a computer or use a local store

The simplest alternative to an online fax service with email fax or a connected fax machine is fax software or finding a local place to send a fax.

Most versions of Windows include “Window fax and scan,” a program that acts as a direct replacement for a fax machine. A fax modem on the computer and a landline phone line are required. This program acts very much like an email client, however, is for sending and receiving faxes.
