A computing device, such as a network server or user terminal, automatically performs one or more predefined actions on inbound email messages responsive to receiving the inbound email messages. However, rather than base the performance of the actions on information manually provided to an email application by the user, the computing device retrieves event-related information stored in one or more calendar applications communicatively connected to the email application. The computing device then utilizes that information to perform the predefined actions. One example of such an action is automatically generating and sending an autoreply email message to the sender of the inbound email message.
