Email fax is a system that allows users to either send or receive a fax through email (sometimes the system can both send and receive, sometimes a system can only send or only receive).
Email faxing is a feature that is available in some internet fax systems. All email fax systems are a type of internet fax. However, not all internet fax systems work through email (some only operate through a web interface or their software).
Three ways to email fax
- An online fax service – most online fax services have a feature of being able to send and receive faxes through email. This service can be set up by signing up for the service.
- A fax server – used in enterprise-level applications, a fax server can be configured to give employees access to fax through email. Fax servers are set up through an organization’s IT department.
- A fax machine enabled with fax to email (and/or email to fax) – some fax machines (often business level machines) can send and receive faxes through email.
