EFax is a service that allows faxes to be sent and received over the internet, essentially making faxing as easy as sending an email. It is supported by J2 Global Communication. Features and pricing are very compelling, some users complain that customer service is less helpful than some competitors. One nice feature of EFax is their desktop application for sending and receiving documents. Most companies in this space only offer web-based management tools.
