# Email to fax

> Send faxes directly from your email without logging into Amplify.

Email-to-fax lets you send documents as a fax by emailing them to a dedicated fax address. This is useful when you want to fax quickly from your email client or automate faxing via email.

## Overview

With Email-to-Fax, you can:

* Send a fax from from Amplify's or custom domain
* Control who is allowed to send faxes by email
* Use email subject and body as fax cover page content
* Attach documents to be delivered as fax pages

## Enable and configure Email-to-Fax

1. Go to **Settings → Fax Settings -> Email to Fax**.
2. Choose who is allowed to send faxes via email:
   * **Not allowed**
   * **Account users only**
   * **Anyone with a verified domain**

<Note>
  Email-to-Fax supports custom domains. After configuring and verifying a domain in **Fax Settings → Email to Fax**, users can send faxes to addresses such as `[faxnumber]@yourcompany.com` instead of the default `[faxnumber]@ifax.com`. This provides a branded and more seamless email-to-fax experience for your organization.
</Note>

1. If domain-based access is enabled, add and verify allowed domains.
2. Save your changes.

<Note>
  Only emails sent from allowed and verified domains or users will be processed.
