An email address is a designation for an electronic mailbox that can send and receive messages on a computer network. It consists of two parts: a local part and a domain. The local part usually contains the username of the user, while the domain name depends on what email service provider is being used. The general format of an email address is local-part@domain, for example, [email protected]. The local part can contain words, numbers, or periods, while the domain name can be any sort of thing, such as a website or a server that allows people to send and receive emails. An email address is a unique identifier for an electronic mailbox that sends and receives messages, known as email, on a computer network. To create a personal email address that will not change as you change schools, jobs, or internet service providers, create an account with an email provider of your choosing, such as Gmail or Yahoo! Mail.
