A computer-implemented method for leveraging social networking information with a messaging client are disclosed. In one aspect, a messaging client (e.g., email client), or an application designed to be closely integrated with an email client, analyzes a message to identify a sender, and then generates a query including information identifying the sender that is forwarded to a social networking application to be processed. The social networking application returns information about the sender (e.g., from a social networking profile), that can be viewed by a user of the messaging client, thereby providing additional information about the sender of a particular message.
