A circuit transmits a beneficiary to a benefits server when a message recipient has disposed of an incentivized message by opening and attending to the message. A navigation and viewport control circuit presents a précis of an incentivized message with a proposed time to disposition (TTD), a proposed disposition, and a proffered benefit for at least minimally engaging with the message; records the time the message is opened; and whether the required minimum has been attained. A message transformation and disposition apparatus retrieves, from a benefit server, a decay or expiration time, a required quantum of engagement, and a proffered benefit. Stored disposition history of recipient and peers is read to determine a proposed disposition and TTD according to user's preferences for benefits and their expiration dates. A timer causes performance of the proposed disposition depending on user's activity or inactivity. Engagement can require passive viewing or non-random interacting.
