Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureYour VIP got a win-back discount. A loyal buyer looks lapsed. A subscriber got your newsletter twice. Duplicate profiles can cause all three. MergeGuard finds duplicate customers by name, email, phone and address and counts each person once. See real VIPs, win back lapsed customers and spot subscribers who may cancel. Fix email typos and sync clean lists to Klaviyo.
Segmently applies your tagging rules the moment an order or customer event happens, and applies those same rules backwards across your entire history in one run. One rule tags the order and the customer behind it, so you stop maintaining the same logic twice. A built-in tag manager shows every tag with exact counts and lets you rename, merge or bulk delete across the whole store.
- Identify duplicate customer profiles
- Review detected duplicates before merging
- Merge customer profiles into a single record
- Maintain customer details and order history
- Backfill any rule across every order and customer you have ever had
- One rule tags the order and the customer behind it, with no duplicated logic
- Tag manager: every tag with live counts, rename, merge and bulk delete
