This document discusses ways for brands to create word-of-mouth marketing through storytelling and engaging customers. It presents two ideas - using maxi-response postcards that customers can send to friends for free, and a mobile postcard app that allows customers to send photo postcards from their phone. Both options give brands control over budgets and ability to measure the impact on sales. The document encourages brands to use these low-cost word-of-mouth strategies for their next marketing event.
