METHODS AND SYSTEMS FOR UPDATING GROUP MAILING LISTS

A mailing list for an associated group of individuals, such as graduates of a college, is updated by requesting information on lost individuals from individuals with known addresses. Results are optimized by automated compiling of customized listings of lost individuals based on analysis of commonality of personal data items (such as class year and membership) between lost individuals and individuals with known addresses. Responses from recipients of the customized listings are used to update mailing list addresses.
