Klaviyo launches Composer, an AI marketing agent for all customers

Statistics on a laptop

Klaviyo has opened its AI marketing agent, Composer, to every customer on the platform. The release adds three distinct capabilities: grounded data analysis, scheduled recurring tasks, and reusable workflow templates called Skills.

What Composer Does

Composer answers questions about your customer, marketing, and commerce data in plain language. Every answer comes with visible citations so you can trace the source. You can ask things like which flows are actually driving revenue, where customers are dropping off between first and second purchase, or whether over-messaging is hurting engagement.

Results are benchmarked against data from more than 205,000 Klaviyo customers, so you get vertical and scale-matched context rather than raw numbers in a vacuum.

“Now, I don’t have to be the only one sifting through so many open rates, so many click rates, and comparing and contrasting trying to find if there’s a date when things started to go wrong. I’ve really been able to tap into AI to help do these audits and find out if there is a canary in the coal mine.” — Shannon Jörgenfelt, senior email and retention manager at Tatcha

Scheduled Tasks and Skills

Composer runs in the cloud 24/7, whether or not you’re logged in. You can schedule recurring instructions: tell it to review top flows every Monday and flag anything slipping, or to compare lifecycle performance across markets on the first of every month and surface the three biggest opportunities.

Skills let teams encode their own processes once and apply them consistently across brands, markets, or team members. The process you define becomes the default, even when you’re not the one running it.

The Operator Angle

For solo operators and small teams, the scheduled task feature is the most practical part. Setting a recurring audit and getting a prioritized fix list removes the need to manually remember to check campaign health. Klaviyo’s announcement also includes two ready-to-use prompts: one that identifies segment gaps from 12 months of purchase history, and one that audits live flows for expired coupons, broken links, out-of-stock products, and any email performing 25% below its 90-day revenue average.

Composer is available now at klaviyo.com/composer.
