Force.com allows emails to be sent and received in Apex code. This functionality can be helpful in many scenarios. For example, you could send an email from within a trigger to notify users of events occurring in the application, such as work that requires their attention. You could write code to automate the classification of incoming emails to customer support, searching for keywords and routing them to the proper support employees. This section describes how to use the objects and methods built in to Apex to process inbound and outbound email and introduces the administration screens of the native user interface that support them.
