Shopify + Kawaa
Validate customer emails on theme pages
Validate emails on Shopify theme pages — cart, customer account signup, contact forms, and custom theme forms — via our JavaScript SDK or REST API. Validating emails at the actual checkout step requires a Shopify Checkout UI Extension; that native app is in development.

Frequently Asked Questions
Can I validate emails at the checkout step?
Not yet via the SDK alone. Shopify's checkout step UI can only be customized through Checkout UI Extensions, which require a published Shopify app. Our native Shopify App with a Checkout UI Extension is in development. In the meantime, you can validate at account creation, newsletter signup, and any custom theme forms via the JavaScript SDK.
Will theme-form validation slow things down?
Verification happens instantly (under 1 second) and doesn't block submission unless you configure it to.
Can I verify existing customers?
Export your customer list from Shopify, verify in bulk with Kawaa, then update tags or segments in Shopify based on the results.
Is there a Shopify App Store listing?
Not yet — a native Shopify app with a Checkout UI Extension is in development. Today, integration is via our JavaScript SDK on theme pages or our REST API for server-side flows.
