Guard your shop

ShopGateKeep lets you block unwanted buyers by setting up validation rules for emails, phone numbers, addresses, and more.

• Email blocklist. Prevent specific email addresses from completing checkout — block bots, fraudsters, and abusive accounts instantly.
• Enforced by Shopify Functions. Validation runs inside Shopify's infrastructure at checkout time — no extra server calls, no added latency.
• More validators coming. Phone number, address, and additional validation types are on the roadmap.
