A system for administering text communications may be configured to determine if an incoming communication that includes text meets any of various criteria and respond based on that determination. A reply may include information based on the criteria or information related to how other messages with the same or similar criteria have historically been handled by a user. Reply communications may be in a different form than that of the incoming communication. Other actions may be taken in addition or instead of replying, including setting calendar reminders or tasks, and sending delegate notifications. Data used for determinations may be collected over time or gathered from external systems.
