Describe a scenario where utilizing a 'utility' message template would be most appropriate, detailing the specific information conveyed and the expected customer outcome.

A 'utility' message template is most appropriately used in scenarios where the communication directly facilitates an agreed-upon transaction or provides updates, alerts, or information specifically requested by the customer. A suitable scenario is providing a customer with a real-time update on the status of their flight. The utility template would convey specific information such as the flight number, scheduled departure time, current status (e.g., 'on time', 'delayed'), updated departure time if applicable, gate number, and boarding information. The 'expected customer outcome' is that the customer receives timely and accurate information about their flight, enabling them to plan their travel accordingly, reduce anxiety about potential delays, and arrive at the correct gate on time. The information is transactional in nature. The customer has an existing relationship with the airline and has requested this type of update by booking a flight. This usage aligns with the purpose of utility templates, which are designed for delivering essential and expected information directly related to a specific transaction or service the customer has engaged in. It avoids promotional content or marketing that would be more appropriate for a marketing template. For example, this template would not include information about discounts on future flights; instead, it focuses solely on the information relevant to their current booked flight. Utility templates are focused on providing essential and expected information.
