Abstract: A communications and data system that is efficient and easy to use and solves potential regulatory and legal problems with the use of current text message systems for delivering non-commercial messages to cellular phones without explicit prior consent from those contacted. It also creates a research platform for investigating the effectiveness of communications to cellular phones. The system includes a database with a contact data file and a contact group. It also includes an administrative function that creates a task to match a specific message to a specific contact group. The administrative function is configured to control message, task and group assignments to enable the execution of methodologically sound randomized-controlled experiments to advance communications research.
