Abstract: An electronic message may be reconfigured to effect an enhanced notification using an input interface to receive at least one electronic message created by or on behalf of a message source for delivery to an intended recipient. A matching engine determines whether the electronic message corresponds to a predetermined definition of an enhanced notification. An enhancement engine reconfigures the electronic message to the enhanced notification if stored information related to the intended recipient indicates that the intended recipient is subscribed to receive the enhanced notification. Reconfiguring the electronic message may include reconfiguring the message to provide special handling, routing or presentation.
