Klaviyo is advancing its vision of an autonomous B2C CRM where brands define desired outcomes and AI agents execute them. The company has introduced Composer, a new agentic experience that generates, optimizes, and recommends complete marketing campaigns and flows from a single prompt, while expanding Customer Agent capabilities and releasing more than 75 new features across marketing, data, and analytics.
With Composer, marketers simply describe their goal in plain language, and the agent builds a complete, launch-ready campaign including audience segments and multi-channel messaging optimized by real customer data and historical performance. For example, a prompt such as “build me a fun spring re-activation campaign, targeting lapsed customers across email and text” produces a ready-to-refine campaign in minutes. The same interface can analyze existing flows and recommend precise fixes.
Composer accelerates execution from days to minutes while ensuring coordinated, context-aware campaigns grounded in more than 14 years of Klaviyo marketing intelligence and billions of consumer interactions. Built-in guardrails require human approval before any campaign goes live, maintaining brand control.
New out-of-the-box skills for Customer Agent enable automated retail service experiences including order tracking, returns and exchanges, subscription editing, and loyalty lookup. These capabilities run directly on Klaviyo’s real-time customer data platform. Agent Guidance further empowers brands to define voice and tone, set communication preferences, and configure precise escalation rules so empathetic or complex interactions are seamlessly handed to human agents.
The launches build on a broader Q1 wave of innovation. New capabilities include general availability of RCS messaging and Instagram auto-replies for richer engagement, Personalized Onsite Banners for code-free website personalization, advanced identity resolution for multi-email profiles, enhanced audience optimization, personalized send time, next-best product recommendations, and new integrations such as WooCommerce for Customer Hub.
“The execution layer in software is moving from humans to agents,” said Klaviyo co-founder and co-CEO Andrew Bialecki. “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.”
