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.
When your store has duplicate customers or email typos, order history splits, emails bounce, and LTV and marketing segments break. Singulary audits your whole customer list: it detects duplicate profiles by name, email, address and phone, scores each match by confidence, and flags invalid emails and incomplete addresses. Merge and fix them in bulk or side-by-side.
