How to Send a Fax from Gmail: 3 Easy Methods (2026)

Quick Answer: Gmail doesn't have a built-in fax feature, but you can send a fax from Gmail using an email-to-fax service like mFax.to. Compose a regular email, address it to the fax number, attach your document, and hit Send — the whole process takes under 2 minutes.

Need to send a fax from Gmail but don't have a fax machine? You're not alone — millions of people use Gmail as their primary email and need to fax documents for work, taxes, or healthcare. The good news: you can send a fax from Gmail without ever leaving your inbox.

Gmail itself doesn't include a fax feature, and Google has never offered one. But with a third-party online fax service, your Gmail account becomes a fully functional fax machine. Below are three methods that work right now in 2026.

Method 1: Email-to-Fax from Your Gmail Inbox

This is the simplest way to send a fax from Gmail — you compose a regular email and the fax service converts it into a fax transmission. No apps to install, no browser extensions needed.

How It Works

An email-to-fax gateway bridges Gmail and the fax network. You send an email to a special address (the fax number + your provider's domain), and the service:

1. Receives your email
2. Converts the attachment to fax format
3. Dials the recipient's fax machine
4. Delivers the document and sends you a confirmation

Method 2: Upload from Gmail to a Fax Web App

If you received a document as a Gmail attachment and need to fax it forward, you can download it and upload to a web-based fax portal.

1. Open the email with the attachment in Gmail
2. Download the attachment (click the download arrow icon)
3. Go to mFax.to or open the mFax app on your phone
4. Upload the document, enter the fax number, and send

This method gives you access to the full fax dashboard — delivery tracking, custom cover pages, fax history, and contact management. It's the better choice when you need to fax multiple documents or track delivery status closely.

Method 3: Gmail Fax Add-ons

Some fax services offer Google Workspace Marketplace add-ons that integrate directly into Gmail's interface. These add a "Send Fax" option inside Gmail without needing to format a special email address.

How to Install

1. Open Gmail and click the Get Add-ons button (plus icon in the right sidebar)
2. Search for your fax provider in the Google Workspace Marketplace
3. Click Install and grant the required permissions
4. The add-on appears as a new icon in your Gmail sidebar

When to Use This Method

Add-ons work best for teams that fax frequently and want a more polished experience. They typically offer a built-in cover page editor, contact picker, and delivery status panel — all without leaving Gmail.

Comparing the Three Methods

For most people, Method 1 (email-to-fax) is the fastest and simplest. You never leave Gmail and the process feels like sending a normal email.

How to Receive Faxes in Gmail

Sending is only half the story. Most online fax services also let you receive incoming faxes as PDF attachments delivered straight to your Gmail inbox.

Here's how it works:

1. Sign up for a fax service that includes a virtual fax number (mFax Business plans include one)
2. Set your Gmail address as the delivery destination for incoming faxes
3. When someone faxes your number, the document arrives as a PDF attachment in Gmail

You can then search, star, label, and archive faxes like any other email. For a detailed walkthrough, see our guide to receiving faxes by email.

Gmail Fax Tips: Labels, Filters & Templates

Once you're faxing regularly from Gmail, these power-user tips save time.

Create a Gmail Filter for Fax Confirmations

1. Search Gmail for from:noreply@mfax.to (or your provider's confirmation address)
2. Click the filter icon and select Create filter
3. Choose Apply the label and create a "Fax Confirmations" label
4. Check Also apply to matching conversations

Now every delivery receipt is automatically labeled and easy to find.

Use Gmail Templates for Repeat Faxes

If you fax the same number regularly (like a doctor's office or the IRS):

1. Enable Templates in Gmail Settings → Advanced
2. Compose your fax email with the To address, subject, and body filled in
3. Save as a template: More options (⋮) → Templates → Save draft as template
4. Next time, load the template and just attach your new document

Organize with Labels

Create labels like "Faxes Sent" and "Faxes Received" to keep your fax correspondence separate from regular email. Combine with filters for automatic sorting.

Is Faxing from Gmail Free?

Gmail itself is free, but the fax service is not. There is no way to send a fax from Gmail for free on an ongoing basis — the fax network requires infrastructure that providers charge for.

That said, faxing from Gmail is significantly cheaper than the alternatives:

Some services offer free trials or a small number of free pages to start. Check our roundup of free fax services for current options. For occasional use, a pay-as-you-go fax plan is the most affordable option.

Is Faxing from Gmail Secure?

Email-to-fax is as secure as your fax provider makes it. The fax itself transmits over the telephone network (PSTN), which is inherently point-to-point. The email leg — from Gmail to the fax gateway — travels over TLS-encrypted connections.

For sensitive documents:

• Choose a provider with TLS encryption for the email-to-fax connection
• Verify the fax number before sending — a misdialed fax goes to the wrong machine
• Use a HIPAA-compliant provider if sending medical records or PHI — the provider must sign a Business Associate Agreement (BAA)

mFax Business plans include encryption, BAA, and audit logging for HIPAA-compliant faxing. If you need to fax sensitive documents, see our guide to fax cover sheet templates — a proper cover sheet adds a confidentiality notice.

Send Your First Fax from Gmail

You don't need a fax machine, a phone line, or a trip to the store. Open Gmail, compose an email, attach your document, and send.

Try mFax.to — set up takes under 2 minutes, and you'll have a delivery confirmation in your inbox before you finish your coffee.
