Klaviyo’s commerce data and AI agent strengths
Generated by Klaviyo AI
Klaviyo was named a Challenger in its first evaluation in the 2026 Gartner Magic Quadrant for Multichannel Marketing Hubs. The post explains its commerce-focused customer profiles, the distinct roles of Customer Agent and Composer, and how Klaviyo Data Platform supports personalized journeys.
- Commerce focus: Klaviyo combines transaction histories, browsing activity, campaign responses, and product reviews into profiles used across email, SMS, push, and web.
- Customer conversations: Customer Agent handles service and sales conversations within brand-defined guardrails, feeding customer preferences and intent signals back into profiles.
- Campaign support: Composer identifies marketing opportunities and builds omnichannel campaigns, with explicit human approval required before launch.
Klaviyo has been recognized in the 2026 Gartner® Magic Quadrant™ for Multichannel Marketing Hubs, named a Challenger in our first year in the evaluation. Gartner named Klaviyo a Challenger, and customers agree: Klaviyo is rated 4.7/5 on Gartner Peer Insights for Multichannel Marketing Hubs.
What Gartner credited us for is exactly what we know large consumer brands are asking for right now: a platform built for commerce, AI agents that do real work across your business, and a data platform that keeps those agents grounded in what your customers are actually doing.
We aren't here to protect legacy software paradigms or maintain the status quo. We're building what consumer brands need to scale profitably.
Built for retail and ecommerce
Gartner recognized Klaviyo as a commerce-centered marketing platform, noting that brands can bring transaction histories, on-site browsing, campaign responses, and product reviews into individual profiles, then activate those profiles across email, SMS, push, and web using built-in predictive analytics.
That focus is intentional. We built Klaviyo around the data commerce runs on: what people browse, what they buy, and what brings them back. It's helped consumer brands drive over $300 billion in attributed value.
For large retail and ecommerce brands, that means Klaviyo already speaks your language on day one, and houses all relevant consumer data necessary for your team to create unparalleled consumer experiences that make your brand stand out.
Two AI agents, working across your entire business
Gartner also named Klaviyo's AI agents, Customer Agent and Composer, a strength. Gartner noted that Composer requires explicit human approval before anything launches, while Customer Agent resolves two-way service and sales conversations on its own, inside guardrails your brand sets.
In the companion 2026 Gartner® Critical Capabilities for Multichannel Marketing Hubs, our strongest use cases were conversational and agent-augmented marketing, and omnichannel workflow innovation.
Gartner pointed to Customer Agent handling both service and merchandising as one agent: it answers product questions, adds items to the cart, and applies promotion rules right in the conversation. What a shopper shares here then becomes reusable audience data, and that context carries over when a conversation moves to a live agent.
We know that managing millions of individual customer relationships across channels is a monumental task. That’s why we split the work between two agents built on one connected customer profile: one that talks directly to shoppers, and one that runs campaigns alongside your marketing team. Neither agent works in isolation, so nothing gets stranded in one channel nor impacts your customer's brand experience.
Customer Agent talks to your customers
Customer Agent handles two-way customer conversations, delivering 24/7 service that also drives real-time sales.
- Resolves support issues and closes sales in the same conversation: Operates as an autonomous brand expert across email, web chat, text, and WhatsApp. It answers complex product questions, guides purchases, and resolves issues without hold times or transfers.
- Continuous profile enrichment: Every conversation automatically enriches the underlying customer profile. Interactions don't stay trapped in support logs. Customer preferences, sizing notes, and intent signals immediately feed back into future marketing flows, discount decisions, and channel targeting.
- New skills, described in plain language: With Agent Builder, your team describes what you want Customer Agent to do, and Klaviyo AI builds the skill. Gartner noted that Agent Builder also tests and ships each skill and logs every change in an audit trail, so your marketers (not your engineers) stay in control of what the agent can do.
- Global and multilingual: Supports over 100 languages with automatic regional locale, pricing, and catalog detection to serve international audiences natively.
Composer works alongside your marketing team
Composer, Klaviyo's AI marketing agent, works like an expert marketer embedded in your team's day-to-day.
- Proactive campaign building: Composer continuously audits marketing performance and identifies revenue opportunities and churn risks. It then builds complete omnichannel campaigns, spanning copy, design, audience segmentation, and flows, in minutes.
- Time back for large teams: Over 126,000 accounts actively use Composer. By automating multi-location coordination and routine campaign builds, brands like Scheels are saving upwards of 32 hours per week on manual marketing work.
- Headless and extensible: Built on the open Model Context Protocol (MCP) and SQL capabilities, Composer connects directly to your custom dashboards and AI tools. It works within your brand guardrails, and nothing goes live without human approval.
How Klaviyo Data Platform powers personalization
AI agents are only as smart as the data behind them. Gartner named our data platform a strength, noting that KDP bridges data storage and multichannel journey orchestration. Two-way sync with your data warehouse lets your team activate segments and custom objects from the warehouse inside your journeys, while the data itself stays centralized and governed.
KDP core capability | What it means for your brand
|
|---|---|
Two-way warehouse sync | Syncs in both directions with your data warehouse, so your team can use warehouse segments and custom objects in journeys without moving data out of a governed home. |
Open ecosystem | Connects to 350+ apps through Klaviyo's marketplace, backed by an MCP server and public API endpoints that let custom agents and external tools build directly on Klaviyo data. |
Real-time data processing | Processes over 4 billion signals daily across 9+ billion profiles, triggering single-customer flows in milliseconds. |
Direct SQL & MCP access | Grants complete data access through KSQL and Model Context Protocol (MCP) servers, letting custom agents and external tools query Klaviyo data seamlessly. |
Dermalogica, the Unilever Prestige skincare brand, puts this to work at global scale. The team used Klaviyo's MCP server and Claude to analyze which skin concerns and customer traits correlated with engagement on two recent product launches, turning that signal into sharper targeting for future launches. Across more than 4 million active customer profiles and over 100 million events processed annually, that data-to-action loop has driven 21% year-over-year growth in CRM revenue.
"Data is king, and we want as much data as possible," said Courtney Wallace, Dermalogica's head of ecommerce. "But if you can't actually turn that data into a revenue-driving, engagement-driving action, then it's just data. Klaviyo makes our data actionable."
The same foundation, beyond retail
Klaviyo's core pillars, unified first-party data, real-time personalization, and agentic AI, apply to any consumer business. That's why we're bringing the same architecture to adjacent B2C verticals, starting with hospitality.
By unifying reservation data, guest preferences, stay histories, and real-time interaction logs into a single profile, hospitality brands are using Klaviyo to deliver personalized guest journeys: automated pre-arrival concierges, front-desk operational dashboards, and more, powered by Klaviyo Headless.
Proper Hotels connects reservation platforms like OpenTable and Toast to a single Klaviyo profile, so the front desk knows the moment a returning guest books a dinner reservation, in time to prepare something special before they arrive. That real-time connection helped Proper Hotels triple its share of CRM revenue in 8 months.
What comes next
Being named a Challenger in our first Gartner® Magic Quadrant™ is a milestone. What matters more to us is what Gartner recognized as our strengths: a platform built for commerce, AI agents that work under your team's guardrails, and a data platform that connects your data to the journeys you run. That's the foundation for what we build next, and it's ready for brands of all sizes.
