Checkout Assurance monitors your store's checkout in real time and sends instant alerts with the customer's name, email, and phone number so you can act instantly.
Cut fake orders and promo abuse from disposable email addresses. Checkout Defense checks the email at checkout and signup against a list of 7,500+ disposable domains, refreshed weekly and checked inside the app with no third-party service. Turn each checkpoint on or off, add allow or block domains, and tag risky signups for review.
