What is E-Mail Address?

Any of several types of addresses that ensure an e-mail message reaches its intended recipient. An e-mail address must contain sufficient information so that the message can be routed to its specific recipient. There are various kinds of e-mail address formats depending on the e-mail system in use.

Address formats typically include at least two parts:

  • A user portion, which indicates the name or alias of the user to whom the mail is directed
  • A routing portion, which indicates the information needed to route the message to the particular mail system on which the user has his or her mailbox

The following table shows some examples of e-mail address formats.
