Embodiments include systems and methods of a service that allows hard copy and electronic media customers to proactively specify, across a broad range of categories, the hard copy mail and/or electronic media mail that they would or would not like to receive. Embodiments include methods and systems configured to allow customers of delivery services to customize the flow of physical items such as hard copy or other letters or parcels, for delivery or electronic media mail from mailers based on highly specific customer-designated criteria. The delivery service acts as a trusted third party to serve as the intermediary between the recipient of the items and mailers to provide privacy and manage a repository for a customer-selected criteria database. In addition, one embodiment provides verification and/or identification that mail being sent meets the customer's designated criteria.
