This document summarizes a research study that explored effective communication strategies for engaging cross-generational alumni of private colleges. The study aimed to identify differences in preferred communication methods, frequency of contact, and effectiveness of communications for Millennial, Gen X, Baby Boomer, and Silent Generation alumni. A literature review found that colleges commonly use social media like Facebook and LinkedIn to engage alumni in a cost-effective way. However, communication preferences and levels of engagement differ between generations. The study sought to understand these generational differences to help private colleges improve their alumni outreach strategies.
