Effectiveness of corporate promotion using SNS will be meaningful from theoretical and practical perspectives. This study attempts to explore the implications of running corporate ambassador programs composed of university students, different from previous studies focused mainly on celebrity influencers. To this end, the research model was generated and the hypotheses were tested by the responses of 287 subjects who received promotional messages from university student ambassadors of a public corporation. Research findings confirmed that ambassador characteristics (intimacy, expertise) had a significant influence on corporate promotion by mediating SNS information characteristics (information provision, information playfulness, and information reliability). Furthermore, it is found that MZ generation perceived the higher intimacy, the higher information playfulness, while the older generation perceived the higher expertise, the higher information reliability. In order to generalize these research findings, further research considering more diverse demographic characteristics is necessary.
