Email Communications Technologies products and their install base

Electronic mail is a method of exchanging digital messages between computer users. Unlike instant messaging systems today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture.
