Email or also known as electronic mail is an internet application, which allows users to exchange messages electronically or through the internet. Email is the diminutive of the word for the English word "electronic email", which in our language the possible equivalent is email; This method allows you to create, send and receive messages through electronic communication systems and nowadays a large part of these systems use the Internet, where “electronic email” is one of the most used on the Internet. It is important to add that emails, or at least a large part of them, allow in addition to sending text, digital documents such as videos, images, audio, among others.
Emails, in their beginnings, were sent directly from a user to a computer, so it was necessary for both computers or computers to be online at the same time, later on, email servers were created that accepted, delivered, stored and they forwarded messages, in this way users would not be forced to be online at the same time.
In order to send and receive these emails, it is necessary to be subscribed to any of these messaging services, where each user is given an address, which is characterized by a symbol called at (@), a symbol that was added by the American Ray Tomlinson, this with the purpose of separating the name of the user and the server in which the user is registered.
The function of an email is similar to that of postal mail, since both allow the sending and receiving of messages, which thanks to an address reach their destination.
