Guides and answers to help you get the most out of Customer Match Lists.
Install the app from your Shopify admin, then open it from the Apps menu. On first open we import your customers and set up your default audiences.
Go to Integration and connect Google Ads, Meta and/or Microsoft. You'll be redirected to each platform to authorize access — no credentials are stored in plain text.
Use the ready‑made default lists or open Customer Match Audiences → Create to build custom segments with AND/OR rules based on spend, orders and sign‑up date.
Under Consider Existing Customers you can backfill historical customers by time period to seed your audiences before ongoing sync takes over.
Each list shows its size, match rate and last sync. The Sync Errors page lists any failures with the reason, so you can fix and re‑run.
Enable scheduled summaries under Get Email Reports. You'll also be emailed automatically if an audience sync fails.
It depends on your customer count. Small stores are usually ready within a few minutes; larger catalogs process in the background and you can keep using the app while it runs.
Match rate depends on how many of your customers have an account on the ad platform with the same email or phone number. Adding phone numbers and keeping customer records complete generally improves it.
Yes. Because your customer lists are synced as audiences, you can use them as exclusions in your ad campaigns to focus prospecting budget on new shoppers.
Read access to customers, orders, checkouts and products — the minimum needed to build accurate audiences. We never modify your store data.
Uninstalling the app triggers Shopify's data‑erasure webhooks and we purge your stored customers, orders, audiences and integrations. You can also email us to request deletion — see the Privacy Policy.
Our team is happy to help with setup, syncing or ad‑account questions.
