# Send eFax by Email Guide

**E-Fax with Email**

1\. Create a new email with the attachments you'd like.

2\. Send the email to the fax number @tofaxnumber.com. The format should look like this: **[1234567890@tofaxnumber.com.](mailto:1234567890@tofaxnumber.com)**

- For example, if you wanted to send a fax to 2485555555, you would send it to [2485555555@tofaxnumber.com](mailto:2485555555@tofaxnumber.com).
