Abstract: An economic-based solution is provided for regulating electronic messages (commonly referred to as spam). Analogous to a standard bond mechanism, delivering email to an inbox requires an unknown sender to place a small pledge into escrow with a third party. If the recipient expects further communication with a particular sender, they can add the sender to a list of approved senders which will allow the sender's messages to be delivered to the recipient. An innovative method for managing this list of approved senders is described in the present application. A technique for soliciting electronic messages using the underlying principles of the bond mechanism is also sent forth in the application.
