How Jack Black built this send — a bestseller discount email shipped as product hero on Thursday at 4pm, carrying a 20% % off offer. Below is Kujola's field-by-field extraction; the original creative is rendered at the end.
20% off — 2.5 points shallower than the tracked set average of 22.5% (this brand averages 17.0% when it discounts).
Voice warmth 0.58 for Jack Black vs 0.70 across the set — a cooler, more clinical register than the average competitor.
