Composer is now available in public beta, built to solve the two problems every marketing team shares: knowing where to focus and not having enough time. Composer identifies the biggest opportunities, builds the campaigns to capture them, and executes the work automatically. Simply ask Composer what to focus on and it runs a full audit of every live campaign, flow, and segment to surface a ranked list of revenue opportunities. Select one, and Composer identifies areas to gain revenue, recommends what to do about it, and then builds the complete cross-channel campaign — email and text, audience and content — drawing on 14 years of customer context, best practices, and patterns from nearly 200,000 brands. Everything happens inside Klaviyo, the campaign is ready to review and launch in minutes, and nothing goes live without approval.
The same customer context that makes Composer smarter is what makes Customer Agent different. Most AI service tools don't know what a customer bought, what's in their cart, or what messages they've received. Customer Agent is different because it starts with the same customer data that powers Composer. Recommendations are sharper because they're informed by the full customer picture — not just what someone asked in service, but every marketing interaction they've engaged with. Because Customer Agent is pre-trained on a brand's data, voice, and policies — and comes with pre-built skills for the most common retail interactions and multi-lingual support — brands can be live from day one with no engineering.
Most platforms keep marketing and service in separate silos. Klaviyo tears that wall down. Built into the Klaviyo CRM platform, both agents work off the same real-time customer profile, and every action enriches the data the other uses. When Customer Agent resolves a conversation, it writes preferences, product interests, and intent signals back to the customer record — data Composer uses to build smarter marketing campaigns. When Composer launches a campaign, that engagement informs how Customer Agent personalizes the next interaction. The more each agent works, the smarter both become, and the result is a flywheel that drives revenue over time.
Jamie Domenici, Chief Marketing Officer of Klaviyo, stated: "Businesses aren't struggling because they lack AI tools — they're struggling because most AI can't act on the context that matters. The next era of consumer experiences will be defined by companies that can combine AI with deep customer understanding to move faster, personalize better, and turn customer insights into growth. Composer and Customer Agent help brands put that understanding to work."
Katherine Cabe, Senior Director of Retention Marketing at AS Beauty, shared: "The visibility Composer provided was unbelievable. It didn't just identify issues, it helped us understand the context behind them. Composer's Flow Audit tool surfaced collision issues across our 113-flow library, showing us where automations were unintentionally competing for the same customers, creating unnecessary message volume, and potential revenue loss."
