Composer audits your flows, segments, and forms to find your best revenue opportunity—and then builds the entire on-brand campaign to capture it, from a single prompt and grounded in your real customer data.
What's new
Composer
Customer Agent
With profile enrichment, every conversation improves your customer data in real time — shopper preferences and intent are written back to the profile automatically, so each interaction feeds sharper segmentation, personalization, and flows.
Customer Agent detects the language a shopper writes in and replies fluently across 100+ languages — on web chat, email, SMS, and WhatsApp. Set it up once in English; there's no separate configuration to maintain for each market.
A new conversational agent builder turns a plain-language description into a working agent: skills, workflows, and logic included. No manual setup, no engineering queue. It's the fastest way to put a new use case live, the same way you'd brief a teammate.
Custom object expansion
Bring data from Snowflake, Databricks, and BigQuery directly into custom objects. Use warehouse data to build segments, personalize content, and trigger flows—right where you build campaigns. No CSV uploads, no middleware.
WhatsApp enhancements
WhatsApp is more engaging than ever. Customers can tap through interactive quizzes and send photos and video right in the chat. Every customer response enriches their profile, so your next message lands sharper.
Website personalization
Show personalized banners, content blocks, and product recommendations to identified visitors across your storefront. Powered by Klaviyo profiles, no custom development needed.
Multi-branch flows
Split a flow into three or more paths from a single decision point, based on any mix of profile properties, behavior, or segment membership. Build journeys that branch by category, value, or lifecycle stage—without nested splits or duplicate branches.
