The Klaviyo integration connects your Klaviyo data to CustomFit.ai so growth and CRO teams can run A/B tests, personalize experiences, and measure revenue impact without engineering work. Instead of exporting CSVs or maintaining brittle scripts, Klaviyo and CustomFit stay in continuous two-way sync β audiences and events flow into CustomFit, and experiment exposures and conversions flow back to Klaviyo.
For D2C and ecommerce brands, pairing Klaviyo with CustomFit closes the optimization loop: you observe behavior, form a hypothesis, build a test or personalized experience in a no-code editor, ship it, and measure the lift against real outcomes. Because evaluation happens at the edge before first paint, the Klaviyo integration adds no visible latency and keeps Core Web Vitals healthy.
Setting up the Klaviyo integration takes minutes, not sprints. Connect via OAuth or an API key, map the fields and events you care about, and turn on sync β every field is configurable, every API call is audit-logged, and you stay in control of data retention. Security is enterprise-grade: SOC 2 Type II, ISO 27001, GDPR and CCPA alignment, with encryption in transit and at rest.
