Ehsan's Analysis
E-commerce NPS has a timing problem that makes most surveys useless. Measured at delivery (the default for most brands), NPS captures the excitement of receiving a package. Measured 30 days later, NPS captures the actual product experience. The delta between these two numbers is the "hype gap" — and it predicts return rates and repeat purchases better than either number alone. Amazon's genius is that their NPS improves over time because the product experience (functional, reliable) matches the purchase experience (fast, easy). Fashion DTC brands show the opposite: NPS peaks at unboxing and drops 20-30 points within a month as fit issues and quality concerns emerge. Track your hype gap. If day-1 NPS exceeds day-30 NPS by more than 15 points, you have a product quality or expectations problem that no marketing can fix.
