The integration brings Wunderkind’s identity insights directly into Klaviyo’s B2C CRM, powering real-time profiles, segments, and flows that help brands recognize more customers earlier in the journey and deliver relevant experiences across email, SMS and other Klaviyo-powered channels.

By layering Wunderkind’s industry-leading Identity Network — built on more than 9 billion device profiles and over a billion unique user identities — into Klaviyo’s unified customer profile, marketers can strengthen their understanding of who customers are, unify identity across channels, and activate personalization through Klaviyo without adding complexity to their tech stack.

“Together, Klaviyo and Wunderkind deliver a future-proof, high-performance solution for brands seeking to maximize the impact, personalization, and efficiency of their messaging programs,” said Richard Jones, Chief Revenue Officer at Wunderkind. “This integration enables brands to activate identity-powered insights directly within Klaviyo, so they can drive smarter decisions, more relevant experiences, and measurable revenue growth — all from a single system of record.”

With Wunderkind now available in the Klaviyo Marketplace, users can:

• Identify more visitors through Wunderkind’s proprietary identity graph, recognizing shoppers across sessions, devices, and brands.
• Grow long-term customer lifetime value through more relevant, consistent experiences delivered through Klaviyo’s native channels.
• Drive incremental revenue through expanded audience reach, higher match rates, and better-timed triggered campaigns.
• Unlock operational efficiency with easy implementation and fast time-to-value.

Brands leveraging Wunderkind’s identity framework have seen up to 8X increases in triggered revenue, while brands using Klaviyo report up to 75% higher lift compared to traditional ESPs when activating personalized, data-driven experiences.
