Sales up 14% at over 99% significance
From Shaw Academy A/B test
Shaw Academy promised a reminder email 3 days before the free trial ends. The reminder lifted sales 14% at over 99% significance. Cancellations did not rise significantly.
The reminder was meant to ease the fear of a surprise charge, a common reason people hesitate to start a trial. Because a reminder could plausibly push people to cancel before billing, Shaw Academy tracked cancellations as a guardrail metric alongside sign-ups. That let them run a bold change while knowing early whether it hurt retention.
