PurposeSocial media has revolutionized marketing communication (MC). Rugby is South Africa’s most professionalized sport, leading the industry in its business management structure as well as its high-performance achievements. However, below the professional level, local rugby clubs face a large disparity compared to their professional counterparts, often relying on volunteers or part-time employees to manage the organizations. Therefore, the purpose of this study is to investigate how non-professional rugby clubs use social media as a MC tool.Design/methodology/approachThe study was exploratory, and a cross-sectional sample of twelve organizations was selected and employed a multiple case study approach. Club managers responsible for MC or social media participated in semi-structured interviews. The qualitative data analysis software, ATLAS.ti, facilitated the researchers’ use of an inductive approach to develop codes and themes for further analysis.FindingsThe findings revealed a high level of adoption of social media by the multiple cases (i.e. rugby sports club respondents), with only slight variations in the usage of specific social media applications (viz., Facebook, Instagram, Twitter, and WhatsApp). The sports clubs perceived that employing social media added substantial value to their MC. There were six emergent themes related to the organization’s perceived benefits from adopting social media MC, namely: brand awareness, relationship-building, player recruitment, attracting sponsors, storytelling, and information sharing.Originality/valueThe study makes a novel contribution in terms of how rugby clubs use social media as an MC tool. The paper advances scant knowledge and awareness of the relationship between South Africa’s sports marketing and social media. The conclusions will aid non-professional sports organizations in enhancing the effectiveness of their social media marketing by ensuring that their objectives and target audiences are well-defined.
