Clean Union ‑ Customer Dedupe

Clean Union finds and merges duplicate customer accounts across your entire Shopify database. Stop sending the same email or SMS campaign to the same person multiple times. Fix broken customer segmentation so win-back and prospect discounts don't go to active customers by mistake. Duplicate customers skew your analytics — churn rates, repeat purchase data, and LTV calculations all become unreliable. This app uses smart detection to analyze all customer data and identify matches. Confidence scoring shows which duplicates need quick review versus deeper scrutiny. Merge dozens of reviewed pairs at once with batch processing. The side-by-side view lets you compare all relevant customer details before merging. Advanced merging safely handles customers with active subscriptions and payment methods. Clean data leads to accurate metrics and better marketing decisions.
