There’s evidence that the 69% of millennials have experienced Fear of Missing Out (FOMO).

A popular strategy is to add a sense of urgency or scarcity to your sign-up form, urging the users to sign up immediately. For example, you can mention that the exclusive promotion is “valid for a limited amount of time,” or that “only the first 1,000 signups will receive free shipping.”. Expiring deals mixes urgency, scarcity, and exclusivity to ramp up that FOMO vibe.
