Vayu Checkout Blocker

Checkout blocker and fraud filter: block customers by email, email domain, country, phone or tag.

Stop orders from buyers you don't want to sell to. Block exact email addresses, whole email domains, disposable email services, shipping countries, states and ZIP or postal codes, phone numbers and customers with a tag such as blocked. You can also block large orders from new customers. A blocked buyer sees your message at checkout and can't pay. Test any buyer in the app first. Rules run inside Shopify checkout, so no theme changes are needed.

• Block emails, email domains and disposable email services at checkout
