When using the '@' symbol in an email address, it is typically placed between the user's name and the domain name. For example, john.doe@example.com. This allows the email system to identify the user and route the email to the correct destination.

Similarly, on social media platforms, the '@' symbol is used to tag other users in posts or comments. For example, if you wanted to mention a friend on Twitter, you could write '@friend'susername' in your tweet, and it would notify your friend that they have been mentioned.

Overall, the '@' symbol has become an essential part of modern communication and is used daily by millions of people across the globe.
