Introduces Composer, expands Customer Agent skills and delivers faster, more trusted customer experiences

Klaviyo (NYSE:KVYO) is building toward an autonomous world where brands define outcomes and agents execute them. Today, Klaviyo took the next step in bringing that vision to life with the introduction of Composer, a new agentic experience that generates, optimizes and recommends full marketing campaigns and flows from a single prompt. Alongside it, Klaviyo added new skills to Customer Agent and continued a wave of platform innovation with more than 75 new features across marketing, data, and analytics.

Composer: Go from idea to launch-ready campaign with just a prompt

With Composer, marketers describe what they want in plain language, and Composer builds a launch-ready campaign, including audience segments and messaging optimized across channels. A marketer could prompt Composer with, "build me a fun spring re-activation campaign, targeting lapsed customers across email and text" and in minutes have a campaign ready to refine and launch. The same conversational interface works for existing flows: ask Composer where a sequence is losing customers, and it tells you exactly what to fix.

Composer provides marketers with:

Faster execution: Campaigns that once took days can now be generated in minutes.
Better outcomes: Coordinated, context-driven campaigns informed by customer data, behavioral signals, and historical performance.
Built-in control: Nothing goes live without human approval.

Every campaign Composer generates is grounded on real customer data and shaped by more than 14+ years of marketing intelligence and billions of consumer interactions - so outputs aren't based on generic best practices, but on what's proven to work across Klaviyo's 193,000 customers.

Composer is currently available in private beta, brands can sign up at klaviyo.com/composer.

Software moves to the autonomous era

For decades, business software has required people to operate tools step by step. AI sped some of that up but people still had to do a lot of the execution. Now instead of operating tools, teams describe the outcome they want to achieve, and agents generate and execute the work within brand and business guardrails.

"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."

"We're seeing a shift from AI assisting discrete tasks to taking on more complete workflows across marketing and customer engagement," said Gerry Murray, Research Director, Marketing and Sales Technology at IDC. "Capabilities like Klaviyo's Composer highlight how quickly this model is evolving, helping organizations move faster while maintaining control over the customer experience."

Customer Agent: Autonomous service built on real-time customer data

Klaviyo also released new out-of-the-box retail skills for Customer Agent — order tracking, returns and exchanges, subscription editing, and loyalty lookup — enabling brands to deliver automated service experiences without custom development or lengthy configuration. Each skill is built directly on Klaviyo's data platform, giving Customer Agent real-time access to the same customer profile that drives a brand's marketing.

Alongside the new skills, Klaviyo introduced Agent Guidance, giving brands precise control over how Customer Agent shows up in every customer conversation. Brands can define their agent's voice and tone, set communication style preferences, and configure escalation rules that specify exactly when Customer Agent should hand a conversation to a human — ensuring that the moments requiring empathy, nuance, or elevated judgment always reach the right person.

Platform momentum: 75+ new features spanning marketing, data, analytics, and customer service

Composer and Customer Agent build on top of a broader wave of Q1 innovation across the Klaviyo platform - more than 75 new features reflecting continued investment in the infrastructure that unifies customer data and the agents that act on it.
