Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for establishing third-party documented trust linkages. In one aspect, a method includes receiving linkage context data from a sending user, creating a linkage context based on the linkage context data, sending the linkage context to the sending user, receiving linkage initiation data from the sending user, sending linkage initiation email based on the linkage initiation data to a recipient user, receiving confirmation opt-in data from the recipient user; and creating a trust linkage between the sending user and the recipient user, where the trust linkage allows the sending user to successfully send at least one future message stream and where the trust linkage allows the recipient user to successfully receive the at least one future message stream. Further aspects include testing trust linkages for processing message streams and destroying trust linkages to stop message streams.
