This paper proposes a conceptual framework for integrating digital health marketing strategies with public health initiatives to enhance healthcare access and outcomes in underserved communities. The framework focuses on leveraging digital marketing tools such as social media, mobile applications, email campaigns, and search engine optimization to disseminate critical health information, promote preventive measures, and engage communities in healthier behaviors. It addresses the persistent challenges faced by underserved populations, including limited healthcare access, low health literacy, and cultural barriers, by utilizing the accessibility and broad reach of digital channels. The proposed framework incorporates three core components: (1) Health Information Dissemination, which explores the use of targeted digital campaigns to provide culturally relevant and accessible health education; (2) Community Engagement, which leverages interactive platforms such as social media and mobile apps to foster participation in preventive healthcare initiatives and healthy lifestyle practices; and (3) Behavioral Change Promotion, which emphasizes using digital tools to influence health behaviors through personalized messaging, reminders, and virtual support groups. By integrating digital marketing strategies into public health programs, the framework aims to improve healthcare outcomes by increasing awareness of preventive measures, enhancing early diagnosis, and promoting disease management. It also underscores the role of data analytics in refining outreach efforts by identifying specific health needs, tracking engagement, and measuring the effectiveness of interventions. This conceptual framework holds promise for healthcare providers, policymakers, and digital marketers seeking to enhance public health outcomes in underserved communities. It provides a structured approach to combining the strengths of digital marketing with public health goals, creating more inclusive, accessible, and effective health interventions. Future research and case studies can build on this model to refine digital health marketing strategies and assess their long-term impact on public health in underserved populations.
