Mail package symbol

You're referring to the package symbol used in email addresses!

The package symbol, also known as the "at sign" or "ampersat", is the "@" symbol. It is used to separate the local part of an email address from the domain name.

For example, in the email address "[email protected]", the "@" symbol separates the local part "john.doe" from the domain name "example.com".

The "@" symbol is a fundamental part of the email address syntax and is used by email clients and servers to route emails to the correct recipient.
