Mail Diary Panel's philosophy is to offer individual tracking studies to meet your objectives in the framework of a syndicated price structure.

MDP is a forerunner in researching the dynamics of consumption, preparation or "use-up" in relation to purchase. Personal coding and editing procedures combine with MDP's advanced computer capabilities to generate in-depth research data that is actionable and reliable.

For over three decades, MDP has extended a personal and ethical commitment to our clients. This has established Mail Diary Panel as one of the most respected tracking research companies in the nation.
