Inclusive go-to-market (GTM) strategies are critical for ensuring that sustainable products and services reach and engage consumers across diverse socioeconomic demographics. This review synthesizes current literature on market access, consumer participation, and sustainability, identifying the barriers and enablers of inclusive GTM approaches. We examine the theoretical underpinnings of inclusivity in marketing, including social equity frameworks and participatory design principles, and assess methodological approaches used to evaluate market penetration among underserved segments. Key components of inclusive GTM strategies—such as tiered pricing, adaptive distribution networks, culturally tailored communications, and multi-stakeholder partnerships—are analyzed through a comparative lens. Drawing on case studies from emerging and developed markets, we illustrate best practices and highlight the role of digital platforms in bridging access gaps. Our findings reveal that successful inclusive GTM designs not only enhance market reach and consumer empowerment but also reinforce sustainable consumption patterns and social value creation. We conclude by proposing a holistic framework for practitioners and policymakers, outlining actionable recommendations for designing and implementing inclusive GTM strategies, and identifying avenues for future research to address persistent challenges in socioeconomic equity and market sustainability.
