Abstract: A method, system and computer program for providing a loyalty engine for automated cause marketing. The method includes a loyalty program system administrator linking merchants and charities to the loyalty system. Members register with the loyalty engine through loyalty system which is accessible via the Internet. Once the merchants and the charities are linked and the members are registered, by operation of the loyalty engine, the merchants can create a customized loyalty program defined by a plurality of merchant defined rules for administering their loyalty program. The merchant defined rules instruct the loyalty engine as to which charities should receive in-kind donations in connection with one or more transactions by a member that is associated to the loyalty program. Once a loyalty system defined time period or donation threshold has been achieved, the loyalty system releases the donation in-kind to the specific charity.
