Purpose In this invited paper, the authors aim to offer an integrated marketing communications (IMC) framework for understanding how disparate customer touchpoints impact consumer engagement and profitability in an omni-channel environment. For each aspect of the framework, the authors recommend areas for further research. Design/methodology/approach The authors review literature linking personal and electronic channels of communication in an omni-channel context to consumer engagement, with an emphasis on channel and message unity. Findings Five major research areas were identified: research that better links omni-channel and IMC theory and practice; conceptual and empirical research that helps operationalize the consumer-brand engagement construct, including its antecedents and consequences; Build understanding of off- and on-line consumer-brand touchpoints and how they may enhance engagement and profitability; how omni-channel IMC best monetizes buyer–seller relationships; and omni-channel IMC in other consumer decision contexts. Practical implications The emergence of omni-channel marketing is breaking down the silos across available consumer-brand touchpoints. The intersection of effective omni-channel marketing and IMC strategic and tactical initiatives offers marketers an opportunity to engage their customers and to form profitable relationships. Originality/value The authors proposed an omni-channel IMC Framework and a research agenda for advancing the field. As this is a new area of inquiry, the authors argue for the development of other comprehensive frameworks, both for general omni-channel IMC conceptualizations.
