Klaviyo
EcosystemMarketing automation platform for e-commerce, integrating with UCP order events to trigger personalized email and SMS flows after agent-initiated purchases.
Klaviyo is the leading marketing automation platform for e-commerce, used by over 130,000 brands for email and SMS marketing. As UCP adoption grows, Klaviyo is extending its event tracking to capture UCP-initiated order events: purchases completed by AI agents on behalf of shoppers.
This integration matters for merchants because it ensures that post-purchase flows (order confirmation, shipping updates, review requests, loyalty point notifications) fire correctly regardless of whether the purchase happened through a traditional checkout or an AI agent session. Without this, agent-initiated purchases could silently bypass the marketing and retention infrastructure that merchants rely on.
Why This Matters for UCP
Klaviyo captures UCP order events to ensure agent-initiated purchases trigger the same post-purchase marketing flows as direct checkout, preserving retention and loyalty programs.

Integration Example
// Klaviyo UCP order event integration
// When a UCP checkout.completed event fires, Klaviyo captures it:
const klaviyo = new KlaviyoClient({ apiKey: process.env.KLAVIYO_API_KEY });
ucpServer.on('checkout.completed', async (event) => {
await klaviyo.events.create({
event: 'Placed Order',
customer_properties: { email: event.shopper_email },
properties: {
...event.order,
ucp_session: true, // tag agent-initiated orders
agent_platform: event.agent_id
}
});
