How to Send a Secure Fax Using Gmail or Outlook — Email Fax Guide

Published · www.ronfax.com

Attach a PDF like a normal email and send from Gmail, Outlook, or business mail — RonFax turns your inbox into an online fax machine for any US fax line.

Still hunting for a shop with a fax machine? Today you can fax the same way you email: attach a PDF, press send, and reach any fax number in the United States. RonFax email-to-fax turns the mailbox you already use into a simple online fax service.

Why send a fax from email?

No new software — Use Gmail, Outlook, or your company email. If you can send mail with an attachment, you can send a fax.

Works everywhere — Laptop, phone, or tablet. If you can read email, you can start a fax job.

Made for real work — Great when you need to forward a contract, a scanned form, or paperwork that arrived as an attachment.

Three quick steps

1. Send the email

Attach your file (PDF or a photo) and send it to:

To: fax@ronfax.com
Subject: the 10-digit US fax number you want to reach — for example 5551234567 (no symbols required; you can write 555-123-4567 if you prefer).

Send the message like any other email.

2. Open the payment link in the reply

Shortly after, you’ll get an automatic reply from RonFax with a secure payment link. Follow that link to complete payment. You can typically use a credit or debit card or options like Apple Pay, depending on what your device offers.

3. We fax and follow up

Once payment is confirmed, RonFax sends your attachment to the fax number in your subject line. When the job finishes, we email you again so you know the outcome.

Common questions

Can I fax a picture from my phone?

Yes. Photos you take with your phone are fine. RonFax converts and optimizes them so they transmit clearly on a fax machine.

How do I know it was delivered?

Your reply after payment includes a link to check status so you can follow progress until the line is done.

Who handles my payment?

You pay on a trusted, secure checkout screen. RonFax doesn’t store your full card details on our servers for routine marketing use.


Tired of digging for “fax near me”? Stay home, use the email you trust, and fax with RonFax.
