Designer Fashion Case Study
How shortyLOVE Switched from a Popular Visitor ID Tool to 3x Accuracy and 5x Revenue per ID with Customers.AI
shortyLOVE, a handbag brand known for stylish, functional designs by a luxury brand powerhouse designer, used a popular website visitor identification tool since 2023. They were satisfied with the provider’s incremental revenue lift for the business, but they kept their eyes open for better identity resolution alternatives.
When they discovered Customers.AI, shortyLOVE ran a head-to-head test comparing it against their long-time solution to find that Customers.AI drove significantly higher data accuracy and match rates, which has since generated stronger revenue performance and better deliverability.
The Challenge
In 2024, shortyLOVE saw warning signs with their visitor ID tool’s data. Klaviyo reports of their Anonymous Site Visitor Welcome Series from April 2024 to July 2024 showed:
- 0.57% spam complaint rate — above Google’s threshold
- 0.1% order rate
- $0.21 Revenue per ID
Facing deliverability risks and underperforming campaigns, shortyLOVE discontinued the visitor ID-powered anonymous welcome series and searched for better solutions to grow their email flow revenue.
The Test
Over March and April 2025, shortyLOVE ran a 1-month head-to-head test between their existing provider and Customers.AI. They compared each platform’s predictions to actual form fill data from 676 verified customers during the test period.

Customers.AI delivered 3x higher data accuracy, meaning shortyLOVE could trust the identities they were targeting.
Part 2: True Match Rate
Next, shortyLOVE calculated the True Match Rate, measuring the percentage of verified customers each provider correctly identified.
Customers.AI’s true match rate was 43x higher, uncovering far more real customers for retargeting and engagement.
Revenue Performance and Email Deliverability
Since switching to Customers.AI, shortyLOVE’s welcome flows to identified visitors have shown dramatic improvements compared to the previous anonymous website visitor welcome series.
