Optimize Shopify Churn Risk with Automated Klaviyo Sync

Transform your Shopify customer retention strategy with this powerful n8n workflow that automatically identifies at-risk customers and syncs critical churn data to Klaviyo for targeted re-engagement campaigns. Stop losing valuable customers by proactively detecting churn patterns before it's too late.

What this workflow does

This automated workflow runs weekly to analyze your entire Shopify customer base and identify those at risk of churning. It fetches customers from the Shopify Admin GraphQL API in paginated batches, calculates each customer's median reorder interval based on their purchase history, and determines churn risk by comparing days since last order against their typical buying patterns. Customers are categorized as MEDIUM or HIGH risk based on configurable thresholds.

Once at-risk customers are identified, the workflow automatically updates their Klaviyo profiles with churn_risk and days_since_last_order properties, enabling you to trigger personalized retention campaigns. A comprehensive CSV report is generated and sent to your team via Slack and Gmail, complete with summary statistics including total customers at risk and potential revenue impact.
