Blocklist

The Blocklist is your store’s permanent “do not fulfill” list. Customers on the blocklist trigger an immediate HIGH score on any new order or return, with the blocklist match as the dominant signal — useful when you’ve seen enough abuse from one person to be done with them.

What gets blocked

The blocklist matches on the Shopify customer account, and a block can also cover other accounts with the same email or phone and the customer’s shipping address. When a customer hits any blocklist entry, every order and refund they generate is automatically scored HIGH, and their orders and returns fire the Blocklisted Customer Order and Blocklisted Customer Return triggers, so your existing Shopify Flow rules can pick it up.

Adding to the blocklist

Two paths: (1) on any customer profile, click Block and add an optional reason; (2) under Settings → Advanced → Blocklist, paste a CSV of emails or phone numbers. The bulk add path is what you use after a fraud incident to clear several offenders in one go.

Removing

The same Blocklist card in Settings lists every active entry with the date added and reason. Unblock is one click and removes the customer immediately. There’s no soft-block / review-first stage — the assumption is that anyone you blocked is fully blocked.

How it differs from the Watchlist

Watchlist is “flag them, but I still want their business.” Blocklist is “I never want to see another order from this person.” The signal is much stronger and the score is forced to HIGH rather than computed, so you can rely on it as a hard gate in your automation rules.

GDPR

The customer record keeps hashes of the email and phone, never the plain email or phone. A GDPR redaction request wipes the customer’s profile from RefundSentry, but the block on their Shopify customer account remains in place.
