Abstract: A method of providing communications to groups of people includes forming a group of people, communicating a product offering to each person in the group, each communication including response information for purchasing the product, using a processor and communication network to identify people in the group that purchased the offered product without using the response information, and using a processor to count the number of persons in the group, the number of product purchases in response to the communication using the response information, and the number of identified people in the group to determine a communication favorability score.
