Klaviyo Composer

Composer is Klaviyo's marketing agent for consumer brands, available to every Klaviyo customer since October 2026. It analyses account data, customer profiles, purchase history and campaign performance against industry benchmarks to surface prioritised opportunities, then builds the audience, content and creative for a campaign or flow across email, SMS, mobile push, WhatsApp and RCS. Every draft is presented for review before it reaches customers, and approved changes are executed inside Klaviyo. Teams can schedule recurring tasks such as weekly flow reviews and save their processes as Skills, and the free plan includes a small monthly Composer usage allowance with paid use beyond it.
