Stop ranking email-capture widgets by opt-in rate — revenue flips the winner
Claspo pored over 100M+ popup views across 51,000 stores and found the metric everyone optimizes is the wrong one. Rank widgets by opt-in rate and gamified wheels win — but the same wheels pull discount hunters who never buy again, while product-finder quizzes collect fewer addresses yet drive more revenue per session. The fix: benchmark against your widget class, not your own baseline.
