Neither the users nor their computers are required to be online simultaneously they need to connect, typically to a mail server or a webmail interface to send or receive messages or download it.

Email servers accept, forward, deliver, and store messages. Today’s email systems are based on a store-and-forward model. The term is a mass noun.Įmail operates across computer networks, primarily the Internet, and also local area networks. Email has become such a ubiquitous (very widely used) communication medium to the point that in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries.Įmail is the medium, and each message sent therewith is also called an email. Email was thus conceived as the electronic (digital) version of, or counterpart to, mail, at a time when “mail” meant only physical mail (hence e- + mail). Electronic mail (email or e-mail) is a method of exchanging messages (“mail”) between people using electronic devices.
