Introducing K:AI Marketing Agent

Disclaimer: K:AI Marketing Agent is currently available in English. Additional languages will be available in 2026.

In today's economy, speed isn't a luxury for marketers. It's survival.

Every week brings a new shift: changing consumer expectations, unexpected competitors, and fresh pressure from leadership to "do more with less." The reality is that most marketers don't lack creativity. They lack time. Time to plan. Time to write. Time to test. And time to scale what works.

The result? Too often, marketing programs are late to launch, limited in scope, or built on guesswork instead of data. And when campaigns do go live, there's little bandwidth left to refine, iterate, and grow.

At Klaviyo, we've heard these frustrations from thousands of B2C marketers. That's why we built something radically different: Marketing Agent, the newest member of K:AI, Klaviyo AI.

Meet K:AI Marketing Agent: AI that launches, scales, and optimizes without prompting

Marketing Agent isn't just another "assistant" that suggests ideas and leaves the execution to you. It's an autonomous AI agent, embedded directly into Klaviyo, that plans, builds, and launches campaigns, flows, and signup forms-always with your oversight and brand guardrails in place.
