Email is short for electronic mail. One can define emails as stored information that you can exchange between electronic devices, such as computers, smartphones, or tablets.
An email may contain attachments, images, and text. The world wide web allows us to send emails through networks to single or multiple recipients. To send or receive an email, you need a valid email address and service.
A valid email address consists of two parts—a username and a domain name, separated by @. For example, email@example.com. The address is used by a sending or receiving mail server.
The server checks whether the provided information corresponds with the information available on the server. If both recipient and sender email addresses are valid, the server should deliver the email.
