The marketing agent that knows—and grows—your business
Built on your customer data, campaign history, and performance signals, Composer spots your biggest growth opportunities and turns them into ready-to-launch campaigns in minutes.

Always on-brand. Always your call.
Composer shows the reasoning behind every recommendation, using the context already in your account to surface the best opportunities to grow. Your team reviews and approves every campaign, while built-in brand and compliance guardrails keep everything aligned with your standards.

Know where to look—without actually looking
Your next best opportunity is probably already sitting in a flow, segment, or campaign—you just don't have time to go looking for it. Composer does the digging for you, surfacing what's worth acting on and prioritizing the opportunities with the biggest revenue impact.

From brief to campaign, in minutes
Describe the outcome you want, and Composer takes it from there. Unlike AI tools that don’t have the context, Composer builds the audience, copy, channels, and timing using your data and brand voice—turning hours of campaign work into minutes.

AI with the inside scoop
Composer doesn't start from scratch. It starts with what it already knows about your business—your customers, products, campaigns, and performance history—and combines that with Klaviyo expertise to deliver recommendations you can feel confident acting on.
