How to Send a Fax Via Email: The Complete Guide to Cloud Faxing

Introduction: Faxing Gets a Digital Upgrade

Imagine someone telling you 10 years ago, “You still need to fax, but you don’t need the fax machine,” you would’ve laughed. But this is exactly where modern business communication stands today. Even though nearly everything, from agreements to prescriptions, has shifted into apps, messengers, and cloud drives, several regulated industries continue to stick to faxing for reasons related to security, compliance, and auditability.

Industries including healthcare, legal, government, real estate, and financial services still need fax because it’s the most secure and legally binding way to transfer documents between parties. But traditional fax machines? They are slow, unreliable, costly, and chained to a physical location.

That’s where Email-to-Fax comes in: It’s an easy and secure way of sending and receiving faxes directly through your existing email account, be it Gmail, Outlook, Yahoo, iCloud, or anything else, and without you ever needing to touch a fax machine, phone line, or toner cartridge.

In this guide, you will discover how to send a fax through email, how the technology functions behind the scenes, how you can receive faxes directly into your inbox, and why selecting the right tool, such as Emitrr, can revolutionize your document workflow.

Understanding Email-to-Fax: The Digital Bridge

Before we start, it’s important to know the underlying technology that makes faxing with email work. This service serves as the “Digital Bridge” between new email technologies and old fax technologies.

What is Email-to-Fax?

Email to Fax is the process of sending a document attached to an email message to a recipient’s traditional fax machine or dedicated digital fax number. Similarly, it’s how you can receive a fax to email.

What It Does

It uses an Internet-based fax service to facilitate document transfer and conversion. This service acts as the central hub.

How the Conversion Happens

Explain what the online fax service does. When you send a fax by email, the service takes in your email, removes any attachment from it, and then converts those digital files (PDF, DOCX, or JPG format) into an analog signal (using T.38 protocol for Fax over IP), before sending them via the public switched telephone network to the machine on the other end. This is how sending a fax via email works: a complex conversion process carried out by the provider.

Fax Address Format

The Standardized Format is the key to the whole thing. Instead of an email address, you enter the recipient’s fax number followed by their service’s domain. For example: [recipient’s fax number] @ [service’s domain]. Using Emitrr, the format would be: 1234567890@emitrr.com.

Receiving Faxes

The other way around is just as easy. Incoming faxes that are sent to your virtual fax number get intercepted by the service. They then convert your incoming files from the analog signal form (fax) to a digital file, typically in PDF or TIFF format, and deliver it directly into your email inbox, where you can safely download it. It’s sort of like receiving a secure fax to email.

Step-by-Step Guide: How to Send a Fax Via Email

Faxing using email is quite easy and simplified; It’s no different from sending an ordinary email attachment. Follow the steps below to know how to send a fax via email.

A. Prerequisite: Get Signed Up for a Cloud Fax Service

Emphasize that a subscription to a secure online fax service (like Emitrr) is mandatory. The email client alone cannot perform the crucial digital-to-analog conversion.

Note that the service only gives you a virtual fax number to receive faxes and an email domain for sending faxes.

Step 1: Compose a New Email

You can use any email client, such as Gmail, Hotmail, iCloud Mail, or Yahoo Mail.
Click the “Compose New Email” button to initiate your transmission.

Step 2: Address the Fax Recipient (The Fax-to-Email Format)

This is the most important part of how to send an email to a fax number.

In the “To” line, enter the full recipient fax number (including country code (if international) and area code), followed by your service’s domain.
Example using Emitrr: [10-digit fax number] @emitrr.com (e.g., 2125551234@emitrr.com).
Emphasize the need for the right number format (no dashes, no spaces, no parentheses). This process answers how to fax from email to a fax number.

Step 3: Attach the Document(s)

Get the document(s) you would like to fax. The service can usually work with common formats such as PDF, DOCX, JPG, and TIFF. This is how to send a fax through email PDF.
Emphasize the convenience: No more need to print documents, you simply attach and send them quickly. This is the core principle of how to send a fax through an email account.
Emitrr Feature Highlight: Mention Big File Sharing: Share HD files and large attachments, up to 30MB each, which is far beyond the tiny limits that traditional fax machines and many competitors can handle, solving issues around how to send a fax through email attachment when the files are large.

Step 4: The Cover Sheet (Optional but Highly Recommended)

Describe how the email Subject and Body are often used as the full text of the fax Cover Sheet.
Emitrr Feature Highlight: Mention about Faxes Sent with a Cover Sheet so that users can use personalized branded cover pages and preview them before they send, making everything look professional.

Step 5: Press “Send” and Verify That Your File Reached Its Destination

Click the “Send” button. Your online fax service takes over, converting the digital file and initiating the transmission.
Explain what happens when you send a fax via email: the sender receives an immediate confirmation email upon successful delivery (or a failure notification if the recipient’s line is busy). This is the electronic record necessary for auditing.
