How to Use Validity Period for Promotional and Verification Use Cases

Validity Period is a feature in Twilio's messaging platform that determines how long messages remain relevant before becoming stale. It ensures users do not receive outdated information due to delivery delays caused by factors such as carrier compliance and service disruptions. The default value for Validity Period is 4 hours, but it can be adjusted based on the specific use case. For promotional messages, a range of 3600-14400 seconds (1-4 hours) is recommended, while verification messages should have a shorter range of 5-300 seconds. It's crucial to set an appropriate Validity Period value to maintain deliverability and avoid delivery delays.
