EFax is advertised as the "largest digital fax network in the world."
Messages sent or received by EFax can be forwarded on to other users quickly and easily.
EFax allows users to choose either a local or international fax number (whichever will best suit their needs).
Using a system like EFax means that customer or client information is not seen by anyone other than yourself and whoever you need to share it with.
EFax customers are charged a flat rate per month to use the service.
