Overview
Klaviyo AI, branded K:AI, is the agent layer inside the Klaviyo B2C CRM rather than a standalone product.
Two named agents carry the work.
Composer is the marketing agent, described by Klaviyo as audit and create flows and campaigns from a prompt.
Customer Agent is a 24/7 service agent that resolves customer conversations, recommends products and writes what it learns back into the customer profile.
Klaviyo says the platform is used by more than 205,000 brands, and the company own site navigation still labels Composer as Preview, so availability varies by account.\n\nFor marketing teams the interesting part is the grounding.
Composer reads the account data already inside Klaviyo, including customer behaviour, engagement, campaigns, flows and performance, uses MCP-powered connections to pull context from the rest of the marketing stack, and then acts on it: it analyses performance, audits campaigns, flows, forms and audiences, builds segments, drafts campaigns and messages, and can be given scheduled recurring tasks that surface opportunities without anyone asking.
Channels cover email, SMS, mobile push, WhatsApp and RCS, and customer-facing work is held for human review before it goes out.
Customer Agent is pre-trained on retail workflows with built-in skills for order status, returns, loyalty, subscriptions and promotions, handles email, SMS, chat and WhatsApp in 113 languages, and takes actions such as checking loyalty points, processing a return or editing an order through pre-built connectors and open APIs.\n\nCost is where a Klaviyo plan gets complicated.
The free tier includes 250 active profiles, 500 email sends a month, five US dollars of mobile messaging and five US dollars of Composer usage.
Composer itself is priced by usage.
Customer Agent is sold by conversation volume: when we read klaviyo.com/pricing on 17 September 2026 the calculator showed 1,000 AI conversations a month listing at 1,000 US dollars and discounted to 700 US dollars under introductory pricing that runs through 30 September 2026, with a one-time free trial of 50 conversations.
Klaviyo also publishes outcome figures, among them 65 per cent of questions resolved without a human and 86 per cent of Customer Agent queries resolved by AI for Naked Wardrobe; those are vendor-reported customer numbers, not our measurement.
The honest limitation is scope: these agents run on Klaviyo data inside Klaviyo, so they are a reason to stay on the platform rather than a layer you can point at another email provider.
Use Cases
Building and auditing email and SMS campaigns from a prompt, with audience, copy and flow drafted before a marketer reviews them
Answering order status, returns, loyalty, subscription and promotion questions automatically across email, SMS, chat and WhatsApp
Turning service conversations into revenue with product recommendations based on purchase history and browsing behaviour
Enriching customer profiles from every conversation so segmentation and personalization improve without manual tagging
Scheduling recurring audits so underperforming flows and fresh opportunities surface weekly without anyone pulling reports
Who Is This For
E-commerce and retail brands already running Klaviyo for email and SMS
DTC teams whose support volume has outgrown the helpdesk headcount
Marketing teams that want agentic automation grounded in first-party customer data instead of a generic model
Retention and lifecycle marketers working across email, SMS, mobile push, WhatsApp and RCS
Global brands that need support and marketing personalization in many languages from one platform
Key Features
Composer marketing agent
Give it the outcome you want and Composer builds the audience, drafts the content and readies the campaign for review, then keeps working on scheduled tasks such as recurring account audits.
Customer Agent service skills
Pre-built retail skills answer order status, returns, loyalty, subscription and promotion questions, and the agent completes the task itself rather than escalating to a person.
Profile enrichment from conversations
Preferences, behaviours and conversation history are captured and written back into the customer profile, so segmentation and personalization improve using data the brand already owns.
Connectors across the customer stack
Customer Agent reaches loyalty and subscription systems including Yotpo, Smile.io, Recharge, Ordergroove and Skio, plus Shopify and a 350-app marketplace, through pre-built connectors and open APIs.
113 languages on four channels
One configuration covers email, SMS, chat and WhatsApp in 113 languages, with configurable guardrails, escalation paths and human handoff triggers kept under the service team.
Pros & Cons
Pros
- Both agents run on first-party Klaviyo data, so purchases, loyalty status, email behaviour and campaign history are available without building a separate data pipeline
- Free tier is usable rather than a trial: 250 active profiles, 500 email sends a month, plus five US dollars each of mobile messaging and Composer usage
- Customer Agent ships with pre-built retail skills and Klaviyo states most brands are live in days because the data and workflows are already connected
- Pricing is published rather than quote-only, including 1,000 AI conversations a month at 1,000 US dollars discounted to 700 US dollars, and a 50-conversation free trial of Customer Agent
- 350-app marketplace plus connectors for Shopify, Yotpo, Smile.io, Recharge, Ordergroove and Skio let the agent act on systems, not just answer questions about them
Cons
- Everything is Klaviyo-bound: Composer requires a Klaviyo account and there is no way to run these agents against another email platform or CRM, so the intelligence does not travel
- Composer is labelled Preview in Klaviyo own navigation, and Klaviyo states access depends on account and usage, so it is not a guaranteed feature on every plan today
- Service pricing scales with conversation volume and the 30 per cent reduction is introductory pricing that the pricing page showed ending on 30 September 2026
- The headline automation rates, including 65 per cent of questions resolved without a human and 86 per cent of queries resolved by AI for Naked Wardrobe, are vendor and customer reported rather than independently tested

Frequently Asked Questions
Editorial Review
Editorial Team

Klaviyo AI is the clearest example we have reviewed of agents working from first-party commerce data rather than from a prompt alone. Composer reads the account and acts inside it, covering campaign and flow creation, audience building, performance audits and scheduled recurring tasks, while Customer Agent resolves service conversations in 113 languages across email, SMS, chat and WhatsApp and writes what it learns back into the profile. The free tier is genuinely usable at 250 profiles and 500 email sends, and the pricing we read on klaviyo.com/pricing on 17 September 2026 is published rather than quote-only, with Customer Agent shown at 1,000 US dollars a month for 1,000 conversations and 700 US dollars under introductory pricing.
Editorial Team

Our reservations are about lock-in and evidence. These agents only run on Klaviyo data inside Klaviyo, so the context and automation you build do not travel to another platform; Composer is still labelled Preview and access depends on account and usage; and the headline outcomes, 65 per cent of questions resolved without a human per the product FAQ and 86 per cent of Customer Agent queries resolved by AI for Naked Wardrobe per Klaviyo, are vendor-reported figures we cannot reproduce. Conversation pricing also scales with support volume, and the 30 per cent discount is introductory pricing that ended on 30 September 2026.
