Klaviyo has made Composer, its AI marketing agent, available to every Klaviyo customer. Describe what you want, like a welcome series or an abandoned cart flow, and it drafts the whole thing: the steps, the timing and the messages inside it.
What it does
- Drafts flows from a prompt. It builds the structure and writes the email, SMS and push messages.
- Audits what you already have. It reviews your campaigns, flows and sign-up forms, then suggests fixes.
- Answers questions about your results using your own Klaviyo data.
Composer was in public beta from June and became available to all customers on 13 October 2026. Klaviyo says there are free and paid options, depending on your account and usage.
Nothing goes live on its own
Composer drafts, you approve. Drafted flows arrive as a preview, and the messages stay in draft until someone signs them off.
Worth knowing: Klaviyo says generated content can occasionally be wrong, and Composer won’t add AI disclosure labels for you.
Newer accounts with little history also get weaker results, because there’s less to learn your brand from.
Before you approve a flow, check:
- Triggers and filters, so the right people enter the flow.
- Every link and discount code.
- Product details, prices and brand voice.
- Send times and audience settings.
What this means for your business
Flows earn their keep. Klaviyo benchmark figures, as quoted by ecommerce agency Optimum7, put flows at nearly 41% of email revenue from just over 5% of sends. If you’ve been putting off a welcome series or abandoned cart flow, Composer makes the first draft much quicker. Just treat it as a first draft, not the finished product.
And with Black Friday close, check your sender setup too. Your Black Friday emails might not arrive if your domain isn’t set up properly.
