Which approach would best enhance customer awareness of a new product?

Promotional advertising is particularly effective in enhancing customer awareness of a new product because it leverages various communication channels like television, radio, online platforms, and print media to reach a broad audience. It focuses on generating interest and excitement around a product, often using persuasive messaging and appealing visuals to grab attention. This type of advertising is designed specifically to inform potential customers about the product's features, benefits, and availability, thus effectively building awareness.

While direct mail campaigns can also reach specific audiences, they often do not have the same broad-reaching potential as promotional advertising. Focus groups are valuable for gathering feedback and insights but do not directly promote a product to the market. Market segmentation involves dividing a larger market into smaller groups based on characteristics, which is useful for targeting but does not inherently create awareness for a new product across the broad spectrum that promotional advertising can achieve.
