Send Faxes Right from Your Business Email

eFax Messenger makes outbound faxing easy and seamless — letting your staff send electronic files for fax delivery directly from within their standard email programs, such as Microsoft® Outlook. Additionally, eFax Messenger uses the most advanced encryption protocols, TLS (Transport Layer Security), for transmitting your faxes.

Also, the delivery of all outbound faxes is confirmed with a transmission receipt and conveniently delivered to the email address of the sender.

Receive Faxes Within Your Business Email

As an inbound fax solution, eFax Corporate supplies each user with a unique fax number capable of receiving faxes, converted either to a .tif or .pdf image file, and delivered to the user’s email inbox as an attachment. These faxes may be viewed using the eFax Messenger tool.
