# Connect Klaviyo to Shopify > Sync your Shopify store data with Klaviyo in real time and run personalized email and SMS campaigns that actually convert. **Canonical page:** https://tray.ai/connectors/klaviyo-shopify-integrations/ **Klaviyo connector:** https://tray.ai/connectors/klaviyo-integrations/ **Klaviyo documentation:** https://tray.ai/documentation/connectors/service/klaviyo **Shopify connector:** https://tray.ai/connectors/shopify-integrations/ **Shopify documentation:** https://tray.ai/documentation/connectors/service/shopify ## Overview Klaviyo and Shopify do different jobs well. Shopify runs your store — products, orders, checkout. Klaviyo takes all that behavioral and transactional data and turns it into targeted marketing. Together, they're the foundation of a serious ecommerce marketing stack. When you integrate them, every customer action in your store — a purchase, a browse, an abandoned cart — automatically triggers the right message at the right time. Manually exporting customer lists, order histories, and product data between Shopify and Klaviyo is slow, error-prone, and stale by the time it's done. A real-time integration means your Klaviyo segments and flows are always working with fresh, accurate Shopify data — so your win-back campaigns, post-purchase sequences, and product recommendations are based on what customers actually did, not a week-old CSV. Brands that connect these two platforms can cut churn, grow average order value, and turn one-time buyers into regulars without anyone touching a spreadsheet. ## Use cases ### Abandoned Cart Recovery When a Shopify customer adds items to their cart but doesn't check out, tray.ai instantly passes that event and cart contents to Klaviyo to trigger a personalized abandoned cart flow. The sequence includes the exact product images, prices, and a tailored incentive to bring the shopper back. This automation is one of the highest-ROI workflows any ecommerce brand can run. - Recover lost revenue with timely, product-specific reminders - Trigger multi-step email and SMS sequences automatically - Segment abandoners by cart value for differentiated offers ### Post-Purchase Thank You and Upsell Flows Every completed Shopify order can trigger a Klaviyo post-purchase flow that thanks the customer, sets delivery expectations, and introduces complementary products. tray.ai passes full order details — SKUs, categories, order value — so Klaviyo can personalize recommendations based on what was actually purchased. This drives second purchases while the brand is still fresh in the customer's mind. - Increase repeat purchase rate with timely follow-up messaging - Cross-sell and upsell using real purchase context from Shopify - Build loyalty through personalized, relevant communication ### Customer Winback Campaigns tray.ai monitors Shopify order history and automatically enrolls customers in a Klaviyo winback segment when they haven't purchased within a defined window. The integration keeps this segment continuously updated as new orders come in or lapsed customers re-engage — so your winback campaigns always hit the right audience without manual list management. - Automatically identify and re-engage lapsed customers - Keep winback segments accurate with real-time Shopify order sync - Reach at-risk customers before they forget you ### VIP and Loyalty Tier Segmentation By syncing cumulative order value and purchase frequency from Shopify into Klaviyo custom properties, tray.ai lets you run dynamic VIP segmentation that updates as customers hit spending thresholds. Klaviyo can then deliver exclusive early-access emails, member rewards, or personalized thank-you notes to your highest-value customers — giving them a reason to stay in that tier. - Reward top customers with exclusive, personalized messaging - Keep VIP segments dynamically updated based on real spend data - Grow customer lifetime value through loyalty-focused flows ### New Product Launch Announcements to Targeted Segments When a new product is published in Shopify, tray.ai pushes product details — title, images, price, category — to Klaviyo and triggers a campaign to the segments most likely to buy based on past purchase behavior. Instead of blasting your entire list, you reach customers who previously bought from a related category first, driving stronger launch-day conversion. - Launch products to high-intent segments instead of your whole list - Automatically populate campaign content with live Shopify product data - Improve launch-day conversion through behavioral targeting ### Refund and Return Experience Management When Shopify processes a refund, tray.ai notifies Klaviyo to suppress the customer from promotional flows and enroll them in a dedicated post-refund sequence focused on resolving their concern and rebuilding trust. This stops tone-deaf promotional emails from going to unhappy customers and creates a real chance to salvage the relationship. A well-handled return can flip a frustrated customer into a loyal one. - Prevent promotional emails from reaching customers mid-refund - Trigger empathetic post-refund flows to rebuild customer trust - Protect sender reputation by suppressing disengaged contacts ### Real-Time Customer Profile Enrichment Every customer interaction in Shopify — new accounts, address updates, purchase milestones — is synced to Klaviyo as profile properties via tray.ai, so your marketing platform always has a complete, current view of each subscriber. Richer profiles mean better segmentation, more accurate predictive analytics, and more relevant personalization across every Klaviyo flow and campaign. No more stale data from manual CSV imports. - Maintain a single, always-accurate customer profile in Klaviyo - Enable granular segmentation using live Shopify customer attributes - Improve deliverability and engagement with relevant, data-backed content ## Templates ### Shopify Order Placed → Klaviyo Post-Purchase Flow Trigger Automatically sends a confirmed order event with full order details from Shopify to Klaviyo the moment a purchase is completed, triggering post-purchase email and SMS sequences with no manual intervention.

Dropped events mean missed post-purchase flows and lost revenue. **How Tray.ai helps:** tray.ai's infrastructure handles high-throughput event streams reliably, queuing and processing Shopify order events without data loss even during traffic spikes — so every order triggers the correct Klaviyo flow regardless of volume. ### Mapping Complex Shopify Order Data to Klaviyo Event Properties Shopify order payloads are rich and nested — line items, variants, discount codes, shipping details, and more — while Klaviyo expects specific event property structures to power its flows and segmentation. Transforming this data correctly requires custom logic that's painful to maintain by hand. **How Tray.ai helps:** tray.ai's workflow builder has a visual data mapping interface and built-in transformation tools that let teams extract, reshape, and correctly format Shopify payload data before sending it to Klaviyo. No custom code required, and updates are straightforward when data structures change. ### Bidirectional Suppression and Compliance Sync GDPR, CAN-SPAM, and other privacy regulations require that unsubscribe and data deletion requests are honored across every system holding customer data. An unsubscribe in Klaviyo needs to show up in Shopify — and vice versa — but the two platforms have no native way to communicate these events to each other. **How Tray.ai helps:** tray.ai automates bidirectional suppression workflows that listen for unsubscribe or data deletion events in either platform and immediately update the corresponding record in the other, so your marketing operations stay compliant without manual intervention. ### Avoiding Duplicate Profiles and Event Deduplication Customers may exist in Shopify as both a registered account and a guest checkout record, leading to duplicate profiles in Klaviyo that skew segmentation, inflate list sizes, and cause customers to receive the same message twice. **How Tray.ai helps:** tray.ai workflows include deduplication logic that checks for existing Klaviyo profiles by email before creating new ones, merging attributes from guest and registered Shopify records into a single, clean Klaviyo profile to prevent duplicate sends and inflated metrics. ## Learn more - Intelligent Integration: https://tray.ai/platform/intelligent-ipaas/ - Merlin Agent Builder: https://tray.ai/platform/merlin-agent-builder/ - Agent Gateway for MCP: https://tray.ai/platform/agent-gateway/ - Book a demo: https://tray.ai/contact/
