This message type includes a countdown timer within your Messenger message. Use this when you want to create a sense of scarcity or urgency around a chosen product. For example, you might send this message out when you’re running a 24-hour flash sale, or if you only have a limited amount of stock and need to sell it quickly. Countdown offers are especially tempting to the hyperactive buyer; those that tend to buy on impulse and enjoy the emotional rush of making a purchase.
