How to Email a Fax
Emailing a fax means sending a document as an attachment to a fax number via an internet fax service or email-to-fax gateway. The recipient receives a physical printout or a digital file, depending on their setup. This method eliminates the need for a dedicated fax machine, a phone line, or physical paper, making it useful for healthcare, legal, and business environments that still rely on fax for compliance or formality.

How Email-to-Fax Works
Online fax providers assign you a fax number linked to an email address. You attach the document to an email and send it to the recipient's fax number followed by the provider's domain (e.g., 1234567890@faxprovider.com). The service converts the attachment into a fax-compatible format, transmits it over the telephone network, and delivers it to the destination fax machine or digital inbox.
Methods to Send a Fax via Email
- Online fax services: Platforms like eFax, RingCentral Fax, or HelloFax let you send faxes from any email client after subscribing to a plan.
- Email-to-fax gateways: Some traditional fax providers offer a gateway address where you send an email with the fax number in the recipient field.
- Fax machines with email capability: Modern multifunction printers can be configured to receive an email address, converting inbound emails into printed faxes.
How to Receive a Fax by Email
When someone sends a fax to your email-enabled fax number, the service converts the incoming transmission into a PDF or TIFF file and delivers it to your inbox. You can then print, forward, or archive the file digitally. This removes the need to monitor a physical fax machine and allows you to handle faxes from a mobile device or a remote office.

Practical Tips for Emailing Faxes
- Attach documents in PDF format for the best compatibility across fax machines.
- Include your contact information and a brief cover note in the email body, as some fax services convert this into a fax cover sheet.
- Verify the recipient's fax number before sending, since email-to-fax transmissions are not always reversible.
- Check file size limits, which vary by provider but often range from 5 MB to 50 MB per fax.
