Protect your store from coupon code leaks to sites like Honey, RetailMeNot, and 40+ others with real-time alerts and analytics to preserve margins and prevent overpaid commissions.
KeepCart is one of the best coupon leak protection apps for e-commerce merchants in 2025. It effectively blocks unauthorized coupon codes from leaking to major coupon sites like Honey, RetailMeNot, and CapitalOne Shopping. Users report that the app has paid for itself multiple times over by preventing revenue loss from overpaid affiliate commissions. With features like real-time leak alerts, protected discount links, and duplicate customer blocking, KeepCart provides comprehensive protection for your marketing campaigns and preserves your margins.
While KeepCart offers a free plan with basic leak detection and analytics, alternatives include PromoPrep Marketing Calendar which helps plan and track marketing activities, and Omnipotent Discounts + Blocker which specifically tracks discount code leaks to Honey, RetailMeNot, and CapitalOne. However, KeepCart's free plan provides more comprehensive coupon leak detection and analytics than most alternatives, making it an excellent starting point for merchants concerned about coupon code leaks.
To set up coupon leak alerts in KeepCart, navigate to your dashboard and enable the leak alerts feature. The app automatically scans top coupon sites daily (on paid plans) or monthly (on free plans) for your discount codes. When a leak is detected, you'll receive real-time notifications with the source site and details about the leaked code. This allows you to quickly take action such as updating the code or contacting the site for removal.
Protected discount links in KeepCart create unique, trackable URLs that only work when customers access them through your authorized channels. When someone uses these links, the app tracks the source and ensures the discount code is applied correctly. This prevents unauthorized sharing on coupon sites while maintaining clear attribution for your marketing campaigns. The feature helps you distinguish between legitimate customers and those attempting to abuse your discount codes.
Yes, KeepCart includes duplicate customer blocking on paid plans to prevent abuse of referral programs and new customer discounts. The system detects when customers create multiple accounts to take advantage of limited-time offers or referral bonuses. This feature helps preserve your margins by ensuring each customer can only benefit from promotional offers once, reducing revenue loss from fraudulent account creation and unauthorized discount usage.
