Which aspect is NOT one of the three main aspects associated with marketing communications?

The primary aspects associated with marketing communications center on how brands convey messages and interact with their target audiences to drive engagement and measure responses. Engagement involves creating meaningful interactions with the audience, encouraging them to participate in the brand's narrative. Audiences are fundamental to marketing communications as understanding and identifying the target demographic is crucial for tailoring messages. Responses refer to the feedback or reactions from the audience, which helps in evaluating the effectiveness of various marketing strategies.

Competitiveness, while important in the broader context of marketing strategy, does not specifically qualify as one of the main aspects of marketing communications itself. The focus of marketing communications is on the relationships and communication flows between brands and their audiences, rather than the competitive landscape surrounding them. Thus, this distinction helps clarify why competitiveness is not one of the core elements associated with marketing communications.
