Have you used a fax machine to receive or send faxes lately? While the answer might be a ‘no’ for many of you, faxing isn’t obsolete yet. Many businesses and companies globally use fax commonly. It’s still an essential means of business communication. As a result, many now use fax-to-email and email-to-fax.

In this article, I’ll explain why fax is still relevant in 2022. I’ll also show you how to send and receive a fax in a more modern way via emails. Finally, I’ll walk you through some of the industry’s leading fax-to-email service providers.

Is Fax Still Relevant in 2022?

Fax (facsimile), or telecopying, is the process of electronic scanning and data transmission to another device. Fax sends data, like text or images, through telecommunication links. The sender fax machines scan the original document as a fixed graphic image. Then, they convert it into a bitmap. After that, they transmit the data in electronic signals through a telephone system to the destination. The destination device then decodes the received electronic data and prints it on paper

As old-fashioned as it sounds, many businesses still use fax. This communication method also provides several benefits. Here are 3 of these benefits

  1. Simplifies the maintenance and organization of paperwork
  2. Is reliable and secure
  3. Provides an effective means of communication as it has no filters to separate inbox and spam

As a result, fax is still relevant in 2022. Additionally, most modern-day faxing solutions have jumped on the internet bandwagon. Now, they use email-to-fax, through computers or smartphones!  Moreover, a multi-functional fax machine can serve as a scanner, printer, and photocopying machine.

Let’s now look at how to send and receive a fax by email or computer.

What Are Email-to-Fax and Fax-to-Email

As the name suggests, email-to-fax or fax-to-email means using an email service to send/receive a fax. Although no device allows you to do that out-of-the-box, you can still enable email-to-fax. I’ll walk you through the 2 most efficient email-to-fax methods:

  1. Enterprise fax server: This is usually found in large corporations with IT resources to manage the servers. It’s also user-managed.
  2. Online fax service: This is a vendor-managed fax system made available as a service. The vendor handles configuration upfront. 

Both methods essentially provide the same functionality and benefits for any business. The major differentiating aspect is your ability and resources. Fax servers require upfront costs to configure. Conversely, a fax service only needs you to pay per user or license.

Let’s now see if you should invest in email-to-fax services.

How Does Email-to-Fax Work

Although these below-mentioned steps vary from vendor to vendor, they’re largely the same. That means you can leverage the needed functionality of sending a fax by email. Simply follow these 5 steps:

  1. Draft a new email that you’d like to fax; add in the content and subject line
  2. Append the ‘to’ fax number with the service provider in the address field. For instance, if the fax number if +1 444 444 4444 and the fax service provider is efax, the email address you need to use will be [email protected]

  1. Attach the necessary documents that you’d like to send with the fax. This step is optional, but you can also add more than documents with an email
  2. Send the email. Once done, the fax service will use its servers to convert email info to fax. Then, it’ll call the fax line
  3. Wait for confirmation from the fax service provider about the content delivery’s success or failure

If your fax delivery fails, make sure you have a stable and connected internet. You can also choose to contact your fax service provider for further assistance. However, if you have your own fax server, then troubleshooting it might be a good option. Examine the spool data for the faxes queued to be sent. 

Now that you know how to email-to-fax, let’s see how you can receive a fax-to-email.

How Does Fax-to-Email Work

Just like email-to-fax, the steps to receive a fax-to-email may vary for each service provider. However, the core functionality and procedure remain the same. Here are the 4 steps for fax-to-email to work: 

  1. The fax service stays in an always-on mode, alert for the fax line to ring
  2. The ringing fax line gets answered as soon as the fax service receives a call. After that, it transmits info sent from the fax sender
  3. Fax content gets stored and rendered by the fax service. It goes to the chosen email or app for you to access
  4. The receiving fax service sends an alert to the sender service to acknowledge the fax reception

If you don’t receive a successfully delivered fax, you can use the acknowledgment or the status of the email/fax to track it. If the issue persists, you can reach out to your fax service provider.
