Klaviyo has been rolling out something called Composer in beta - an AI agent that promises to build entire marketing campaigns from a single prompt. Audience, copy, design, segmentation, all of it. The promise is impressive.
So I got access on a real client account and tested it myself. And my honest take is more nuanced than the hype - and more useful than the skeptics would have you believe.
The short version: Composer is less an autonomous agent and more a really well-informed assistant. It knows your account data better than any outside AI tool could. It just still needs you.
Where it genuinely surprised me was the data side - send time recommendations backed by actual account history, revenue per recipient, open rates by date, flagging which sends had enough volume to be statistically meaningful. That's marketing expert level analysis, and it's specific to your account in a way that ChatGPT or Claude simply can't replicate without a direct integration.
Where it fell short was the creative side. The copy was functional but generic. The design pulled image slices from across the account that didn't really hang together. Getting it to feel on brand would have taken enough back and forth that I may as well have just written and designed it myself.
In this episode I walk through exactly what happened when I tested it, what genuinely impressed me, where it still needs a human, and how to think about using it if you get access.
✨ In this episode, you'll learn:
What Klaviyo Composer actually is and what it promises to do
What happened when I tested it on a real client account with a real campaign prompt
Why the creative output is a starting point, not a finished product
The limitation that affects accounts where most emails are designed in Figma or Canva
The one thing Composer did that genuinely surprised me - and why it matters
Why the send time analysis is where this tool actually earns its place
What to watch out for with the auto-populated segmentation suggestions
How to think about the human vs. AI division of labor in your email program right now
Let it handle the data. You handle the creative direction and strategy. That framing is really useful for anyone thinking about where AI fits into their email marketing going forward.
