Case Study: Just Add Water System (JAWS) doubles subscriptions with Quartile Promo Management

How JAWS Doubled Subscriptions with Quartile Promo Management

Just Add Water System (JAWS), a sustainable home cleaning brand, was looking to turn its natural repeat-purchase behavior into a stronger growth strategy on Amazon. While the company already had loyal customers and a differentiated refill-pod product, its promotions were not yet structured to support acquisition, trial, and long-term retention in a crowded household category.

Quartile implemented its Promo Management solution to align promotions with advertising and customer behavior, using tailored offers, coupons, and Sponsored Products campaigns to drive new-to-brand orders and Subscribe & Save adoption. The result was a 150% increase in active Subscribe & Save subscriptions, a 62% rise in new-to-brand orders, and a 12% improvement in combined advertising and promotional efficiency, along with reported gains in ROAS, ad sales, and reduced ad spend.
