Disclosed embodiments provide a computer-implemented technique for filtering electronic communication based on the current task of a user. The current task of a user is derived using a workflow segmentation model. A workflow segmentation model is derived based on user-defined activities, heuristics, location data, environmental data, and/or other input data. Prior to delivery, electronic communication directed to the user is analyzed based on sender, subject, message content, time of day, and/or other criteria to determine if the message should be presented to the user immediately, or deferred, based on the relevance of the message to the current task of the user.
