An email address is made up of three parts. The first part is the username, which is followed by the @ symbol. The last part is the domain name. The username is the name you choose for yourself when you create an email account. It can be anything you want, as long as it’s not already taken by someone else. The @ symbol is used to separate the username from the domain name. The domain name is the website address that your email account is associated with. For example, if you have a Gmail account, your domain name would be gmail.com. You can also have your own domain name for your email account, which would be something like yourname@yourdomain.com.
