Abstract: The invention is directed to techniques for generating marketing information based on non-purchased items of a gift registry. A system is described that includes a database to store data identifying items registered by a customer in a gift registry. The data identifies whether the items of the registry have been purchased. A generation module generates marketing information for a customer based on the data. A data-mining module selectively retrieves the data from the database, and communicates the data to the generation module. The data-mining module selects items from the registry, and possibly non-registry items, based on a variety of factors, such as retail cost of the items, profit margin of the items, a manufacturer of the items, customer loyalty data, and a profile of the customer that may include demographic information as well as spending pattern data for the customer.
