The Internet and AI tools are transforming marketing communications within a complex, interactive landscape called the echoverse. While marketing has evolved since the proliferation of the Internet, in the echoverse, a diverse network of human and nonhuman actors — consumers, brands, AI agents, and more — continuously interact, influence, and reshape messages across digital platforms. Traditional one-way and two-way communication models give way to omnidirectional communication. The authors integrated communication theory and theories of marketing communications to create a typology of marketing communication strategies consisting of three established strategies — 1) promotion marketing, 2) relationship marketing, and 3) customer engagement marketing — and their proposed strategy, 4) echoverse marketing. The authors also recommend three strategies for marketers to make the shift from leading messaging to guiding messaging: 1) Enable co-creation and co-ownership, 2) Create directed learning opportunities, and 3) Develop a mindset of continuous learning.
