About the AddressPill: Address Validator

AddressPill helps merchants detect and fix invalid shipping addresses during and after checkout. The app validates addresses in checkout without blocking conversions, then automatically corrects issues after purchase. This reduces failed deliveries, returns, and support requests caused by incorrect customer input. Merchants can set up customer self-correction flows to notify buyers about address problems before fulfillment. With built-in triggers and Shopify Flow integration, stores can create custom automations to update orders and prevent shipping errors. The app works seamlessly to fix invalid addresses and cut down on delivery failures and support costs.
