Klaviyo said on October 13 that Composer, its AI marketing agent, is now available to every Klaviyo customer. The company is pitching Composer as a tool that analyzes a brand’s own data, points to what needs attention and drafts the work, from flow audits to new segments.

“Starting today, Composer is now available to every Klaviyo customer,” Klaviyo said in a blog post by Elias Torres, who became the company’s chief product officer in August 2026. A release note on the Klaviyo Community forum published the same day said Composer had come out of preview on October 6.

What Composer does

According to Klaviyo, Composer analyzes customer, marketing and commerce data and answers questions “with visible, verifiable citations” so users can see where an answer came from. The company said results can be compared with industry benchmarks “collected across more than 205,000 customers.”

Two features are aimed at repeat work. Scheduled tasks “run in the cloud to monitor performance and surface opportunities even when users are not logged in,” the company wrote. The release note gave examples such as a Monday review of top flows and a first-of-the-month lifecycle comparison across markets. A feature called Skills lets teams teach Composer a process once and reuse it across teams, brands and markets.

Klaviyo’s sample prompts show the intended use. One asks Composer to audit all live flows for expired coupons, broken links, out-of-stock products, draft messages inside live flows and emails whose revenue per recipient is 25% below their 90-day average, then produce a ranked list of fixes. Another asks it to suggest five new segments with messaging angles and create only the ones the user approves.

The agent’s drafting role predates general availability. In an August 4 post, Klaviyo said Composer could draft flows, segments and push notifications from a single plain-language request, writing messages across email, push and SMS/MMS. That post said every output is a draft to preview, edit and approve, and stated: “Nothing publishes without your review and approval.”

SQL behind the answers

The same release added SQL to Klaviyo Data Platform, which the company said powers Composer’s upgraded analysis. Before the change, Composer could only answer questions covered by pre-built skills for flow audits, campaign performance, segment analysis and form analysis, according to the release note.

The new feature converts a plain-language question into a SQL query using Klaviyo’s own definitions, for example of revenue, runs it against the account’s data and returns the answer together with the definition and query used. It can be reached through Composer or through the Klaviyo MCP (Model Context Protocol) server from outside tools such as Claude or ChatGPT. The release note’s author recommended checking early results against a trusted number.

On cost, the release note said Composer is available on both a free plan and a paid plan and pointed readers to Klaviyo’s pricing page. It did not list usage limits or credits.

Other items in the release

  • Social Performance: a report that links Instagram comments, direct messages, tags and Auto Reply subscribes to a profile’s purchase history and reports orders and revenue, tracked separately from Klaviyo Attributed Value.
  • Customer Agent multi-geo: detects a shopper’s Shopify Market and recommends products from that market’s catalog at its price and currency. It requires Shopify Markets.
  • Multiple RFM models: up to four recency, frequency and monetary (RFM) models in one account, for eligible plans with at least 500 customers who have placed an order.
  • Canadian dollar billing: new Canadian customers can see pricing, sign contracts, pay and receive invoices in CAD.

Klaviyo’s post quoted Shannon Jörgenfelt, senior email and retention manager at Tatcha: “Recently, I’ve gotten access to more tools like Composer and that’s made my life so much easier.”

Why it matters

For merchants running email and SMS programs on Klaviyo, Composer is now a standard part of the account rather than a preview feature. The examples Klaviyo chose, such as catching expired coupons or out-of-stock products inside live flows, target routine upkeep of automated flows rather than only the creation of new campaigns.

The emphasis on citations, visible SQL queries and approval steps reflects a practical concern with AI analytics: whether answers can be checked. Klaviyo’s own release note advises users to verify early SQL results against numbers they trust, and its August post said drafts do not publish without review.

The caveats

All details come from Klaviyo’s announcements. The company did not publish independent results or performance data for Composer. Its figures for data scale also vary by post: the October announcement cites benchmarks across more than 205,000 customers, while the August post cited first-party data from 196,000 brands. Some features in the release depend on specific plans or integrations.
