In some aspects, the techniques described herein relate to a method including: identifying, by a processor, an object included in a message addressed to a user; inserting, by the processor, an explicit feedback control in the message, the explicit feedback control associated with the object; delivering, by the processor, the message including the explicit feedback control to a client device of the user; and receiving, by the processor, feedback from the user in response to an interaction of the user with the explicit feedback control.
