Klaviyo has launched Composer, an AI-driven tool that creates and optimizes full marketing campaigns and flows from simple prompts.
Composer enables marketers to generate launch-ready campaigns in minutes, using real customer data and historical performance to ensure effective, coordinated messaging across channels. The platform emphasizes human oversight, requiring approval before any campaign goes live, maintaining control and quality.
With this release, Klaviyo is advancing toward autonomous business software where agents execute marketing tasks based on desired outcomes, reducing manual operation.
New Customer Agent features include automated retail service skills like order tracking, returns, subscription edits, and loyalty lookups, all powered by real-time customer data. Agent Guidance allows brands to customize the Customer Agent’s communication style and set escalation rules to ensure sensitive interactions are handled by humans.
Enhancements in data identity resolution and personalization tools help brands unify customer profiles and deliver more relevant, timely experiences. New integrations, such as WooCommerce for Customer Hub, broaden Klaviyo’s ecosystem connectivity, facilitating seamless data and workflow management across popular tools.
Klaviyo co-founder and co-CEO Andrew Bialecki, said:
“The execution layer in software is moving from humans to agents. What matters now is having both the agents that do the work, and the infrastructure that gives them the full picture of the customer. That’s what we’re building at Klaviyo.”
Klaviyo introduced over 75 new features in Q1 2026, enhancing marketing, data management, analytics, and customer service capabilities. The platform expanded channel support with RCS messaging and Instagram auto-replies, improving real-time customer engagement.
Gerry Murray, Research Director at market intelligence company IDC, said:
“We’re seeing a shift from AI assisting discrete tasks to taking on more complete workflows across marketing and customer engagement. Capabilities like Klaviyo’s Composer highlight how quickly this model is evolving, helping organizations move faster while maintaining control over the customer experience.”
