How Checkmate's Cashback Drove a 4.2% AOV Uplift for Zulily

By adding Cashback to an already well-performing Enrichment campaign - two levers of the same Performance Network - Zulily gave every shopper a reason to spend more and come back, standing up a loyalty engine that lifted basket sizes from day one.

The Opportunity: One Lever Was Already Winning

Zulily was already a Checkmate success story. Enrichment, one lever of the Performance Network, had quickly become one of the brand's most efficient acquisition channels, delivering its leading purchase rate. Through June 2026, it had added over 50K new emails and maintained 378K identities.

The next question was a natural one: how do we get those shoppers to spend more and return? With Enrichment already converting strongly, the team wanted to layer on a loyalty mechanic that also lifted basket size - without adding cost, complexity, or a separate platform to manage.

Solution

Zulily activated Cashback, a second lever of the Performance Network, and put the Cashback Widget live at checkout. Every shopper, regardless of acquisition channel, became eligible for a cashback offer redeemable on their next Zulily purchase - sponsored by Checkmate.

The impact showed up immediately in basket size. Shoppers who saw the widget at checkout spent more per order, driving a 4.23% lift in average order value. The mechanic was simple: shoppers earned real money back on a qualifying purchase, sponsored by Checkmate, redeemable on their next order, giving them a reason to add more to the cart now and come back later. A single transaction became a loyalty loop.

Because both levers run inside one network, they compounded. For shoppers already receiving a personalized Targeting offer, Cashback stacked on top, layering a return incentive over the offer they had just unlocked. And with Zulily now featured across Redemption Flow and Featured Picks inside the network, the brand sat in front of 5M+ active shoppers - turning a single checkout incentive into reach, loyalty, and net-new revenue at once.

Enrichment brought the shoppers in. Cashback gave them a reason to spend more and return, and the network put Zulily in front of millions more - each lever multiplying the last, with no new tools to manage.
