How JAWS Doubled Subscriptions with Quartile Promo Management

Just Add Water System (JAWS) is a pioneer in sustainable home cleaning. The brand delivers ultra-concentrated cleaning solutions in refill pods that customers mix with water at home—eliminating the need to ship water and significantly reducing single-use plastic waste.

This approach has helped JAWS divert millions of plastic bottles from landfills while delivering powerful, streak-free cleaners that are safe for families, pets, and the environment.

The brand’s commitment to sustainability and smart product design has built a loyal customer base and positioned JAWS as an innovator within the household cleaning category. On Amazon, the brand focuses on growing long-term customer relationships through refill-based products that naturally encourage repeat purchases and subscription behavior.

The Challenge

JAWS had already built a differentiated product and a strong base of loyal customers.

Many shoppers who discovered the refill system returned regularly to reorder pods, creating a natural opportunity for Subscribe & Save adoption and long-term retention.

However, the brand was competing in one of Amazon’s most saturated household categories, where established brands invest heavily in advertising and promotions to capture visibility.

While JAWS had strong product differentiation and repeat purchase behavior, promotions had not yet been used as a coordinated growth strategy. Offers existed, but they were not structured around clear customer acquisition and retention goals.

This created an opportunity: if promotions could be aligned with the customer lifecycle—bringing new shoppers into the brand and encouraging repeat purchases through subscriptions—JAWS could strengthen both growth and efficiency without relying on large increases in advertising investment.

Why Quartile

JAWS partnered with Quartile to turn promotions into a structured growth strategy rather than a series of isolated discounts.

Through Quartile’s Promo Management solution, promotions could be planned, executed, and optimized as part of the broader advertising strategy. Instead of running promotions independently from advertising, Quartile connects promotional incentives directly with campaign performance and shopper behavior.

For JAWS, this meant promotions could now support three critical objectives simultaneously:

• Attract new-to-brand shoppers

• Encourage first-time trial of the refill system

• Convert those customers into long-term subscribers

Quartile’s platform and strategic support allowed the brand to move beyond ad optimization alone and begin treating promotions as a core driver of acquisition, conversion, and retention.

For a brand built around repeat purchases, this approach unlocked a powerful new growth lever.

The Solution

Quartile launched a Promo Management pilot designed to align JAWS’ promotions with the way customers discover, try, and repurchase its products.

Rather than relying on occasional discounts, Quartile implemented a structured promotional framework built around different stages of the customer journey.

Brand Tailored Promotions and tiered offers were introduced to encourage new-to-brand shoppers to try the refill system. These incentives helped lower the barrier for first-time purchases while increasing the brand’s visibility among shoppers searching for eco-friendly cleaning solutions.

At the same time, coupon-based promotions were deployed to support repeat purchases and increase Subscribe & Save adoption. Because JAWS products naturally require replenishment, these promotions reinforced the behavior of returning customers and encouraged them to convert into recurring subscribers.

To maximize the impact of these promotions, Quartile aligned advertising campaigns with promotional activity. Dedicated Sponsored Products campaigns were created to target high-performing promotional audiences and ensure offers appeared when shoppers were actively searching within the category.

Meanwhile, branded keyword protection remained a priority, ensuring that shoppers already familiar with the brand could easily find JAWS products without being intercepted by competitors.

By connecting promotions, advertising, and customer behavior, Quartile transformed promotions into a coordinated growth engine supporting discovery, conversion, and retention.

Results & Impact

Across the first seven months of the program, the strategy delivered strong improvements in both growth and efficiency:

• Active Subscribe & Save subscriptions increased by 150%, growing recurring revenue and strengthening retention.

• New-to-brand orders increased by 62%, expanding customer acquisition in the category.

• Combined advertising and promotion efficiency improved by 12%, reducing the overall cost of driving sales.

Together, these results demonstrated how a structured promotions strategy can amplify both acquisition and retention.

By aligning promotions with advertising and customer behavior, Quartile helped JAWS convert first-time shoppers into long-term customers while maintaining strong marketing efficiency.

Ongoing Value & Future State

With Promo Management now integrated into its Amazon strategy, JAWS has established a repeatable framework for customer acquisition and retention.

Promotions are no longer isolated discounts—they are now a coordinated component of the brand’s growth strategy, helping introduce new shoppers to the refill system and convert them into long-term subscribers.

As JAWS continues expanding its presence on Amazon, Quartile remains a strategic partner helping the brand refine promotions, optimize performance, and scale its sustainability-driven business model.
