Everyone's going to use Klaviyo's new AI agent to write more emails. That's the wrong first move. Your store doesn't need more emails. It needs the flows you already have to stop leaking money.
What Klaviyo shipped
Klaviyo's October release notes say Composer, its AI marketing agent, went generally available on October 6, 2026. It's now out of preview and available to every Klaviyo account, on both a free and a paid plan. Klaviyo didn't list prices in that post and points to its pricing page.
What the GA version does, per Klaviyo:
- Reasons across more of your customer, marketing and commerce data than the preview did.
- Shows citations for the data behind its answers.
- Compares your results against benchmarks drawn from more than 205,000 customers.
- Runs on a schedule in the cloud, even when you're logged out. Klaviyo's examples: a weekly review of top flows, a monthly lifecycle comparison across markets.
The same release added SQL in Klaviyo Data Platform. You ask a question in plain language, it writes the SQL using Klaviyo's own definitions (like how it counts revenue), and returns the answer, the definition and the query. Klaviyo itself recommends checking early answers against a number you trust. Good advice.
Back in June, Klaviyo's launch announcement described Composer as an agent that audits your live campaigns, flows and segments, ranks the revenue opportunities, and then builds a campaign for you to review. Nothing goes live without your approval.
Why "audit first" is the money move
Here's what we see in most Klaviyo accounts we open. A welcome flow built three years ago. An abandoned cart flow that collides with a browse abandonment flow, so the same shopper gets two emails in an hour. A post-purchase flow that still promotes a product you discontinued. A winback flow nobody remembers turning on.
None of that shows up as a big red error. It shows up as slowly falling flow revenue and a rising unsubscribe rate. That's the stuff an always-on auditor is good at catching, and it's where the money is. Your flows run every day on every shopper. A fix there pays off on every order going forward, while a new campaign pays once.
One of Klaviyo's early beta brands, AS Beauty, used a flow audit to check a 113-flow library for collisions, according to the June announcement. You probably don't have 113 flows. But if you have 15 and nobody has looked at them together in a year, you've likely got collisions too.
Our honest opinion: an AI that writes campaigns is nice. An AI that tells you, every Monday, which flow broke last week is worth a lot more to a small team.
The new SQL feature backs this up. Before, asking "which flow lost the most revenue per recipient since summer?" meant exporting data or bugging an analyst. Now you can ask in plain language and see the query behind the answer. For a two-person marketing team, that's the difference between checking flows once a year and checking them every week.
Your first-week Composer plan
- Ask for a full flow audit. Start with something like: "Audit all my live flows. Show overlaps, conflicts and flows with falling revenue per recipient over the last 90 days." Read the citations.
- Check the benchmark gaps. Ask where your flows sit against the benchmarks. Focus on the two biggest gaps, not all of them.
- Verify one number by hand. Pick one figure Composer gives you, like last month's abandoned cart revenue, and check it in your normal reports. If it matches, trust goes up. If not, find out why before you act.
- Fix collisions before writing anything new. Add filters so a shopper in the cart flow skips browse abandonment. Set smart sending windows. This is boring work with real returns.
- Schedule a weekly flow review. Use the cloud scheduling to run the same audit every Monday. Make one person responsible for reading it.
- Only then, let it build a campaign. Pick the top opportunity it ranked, let it draft, and edit hard before you approve. Brand voice is still your job.
Two cautions
Don't skip human review. Klaviyo built approval into the workflow for a reason, and a fast mistake to 40,000 subscribers is still a mistake.
And watch your sending volume. If Composer makes it easy to launch more campaigns, it also makes it easy to over-mail your list. More sends to the same people usually means more unsubscribes and worse deliverability, not more revenue.
The takeaway: let Composer fix the flows you've got before it writes the campaigns you don't need.
