1. Username
The username is the first part of an email address. Back in the early days of the Internet, people chose fun usernames like “musicfan156” or “blueeyes563” that described their hobbies or personalities. But now that email is so prominent in the professional world, usernames tend to include the person’s real name or initials. For example, Javier Martinez is more likely to be taken seriously as “jmartinez” than as “heavymetallover42628.”
2. @ Symbol
The @ symbol, which means “at,” separates the username from the rest of the email address. It means that the username belongs to the domain on the other side of the @ symbol. A server receiving the email uses the @ symbol to determine into which mail server it should sort the incoming message.
3. Mail Server
The name of the person’s mail server is on the right side of the @ symbol. It indicates the organization that hosts the server where their emails go. Many companies create their own domain names for their employees to use, while other domains are available for personal use (for example: Gmail, Yahoo, Outlook).
4. Top-Level Domain
The mail server and top-level domain (TLD) combine to make a user’s domain name. The top-level domain tells users what type of organization they are emailing. There are six common top-level domains:
• .com – company
• .edu – educational institution
• .gov – government institution
• .org – organization
• .net – network
• .mil – military
