Faxing via email is possible with our email to fax feature. If you do not have this feature enabled on your account and would like to have it, please contact us to set it up.

Sending an Outbound Fax by Email

Using any email client, you can send your fax to any 11-digit US number using the format number@instant-fax.com (ex:12033045246@instant-fax.com).

Fax Caller ID When Sending an Outbound Fax by Email

You can have a Fax Caller ID configured to your email address when sending an outbound fax. Please submit a ticket for this request.

Multiple Attachments

It is possible to attach multiple files in your email to fax. The files will all be combined into a single PDF document, based on an alphabetical file name sorting. With this in mind, if you want your cover sheet to be first, name your document file something like 1CoverSheet.doc to ensure it is sorted first, followed by other documents you may also have attached.

The system accepts the following files formats: html; pdf; doc; docx; odt. If you have an Excel file, please save it as a PDF first and then attach.
