Vayu Checkout Blocker

The Vayu Checkout Blocker app allows ecommerce merchants to block customers by email, domain, country, phone, or tag at checkout to prevent fraud and unwanted sales. It provides detailed options to stop orders from specific buyers, including blocking email addresses, domains, countries, phone numbers, and customers with specific tags. The app offers the ability to test buyers within the app and runs rules directly within the Shopify checkout process without requiring theme changes.
