Colleges are better at managing relationships with Champions than they are with Acquaintances. The study identified three segments of alumni - Champions, Friends, and Acquaintances - based on their attitudes and motivations toward giving. Champions are the most important segment for colleges to target as they donate the most frequently and make the largest donations. While colleges have had some success with Champions, they ineffectively manage the large Acquaintances segment and waste resources contacting them as much as the other segments. Effective alumni communications require research-based segmentation, personalized messaging tailored to each segment's motivations, and continuous testing and evaluation of communication strategies.
