How We Verify Promo Codes & Deals

Every offer published on MintVerify Coupons goes through an automated multi-step verification and quality pipeline before appearing in our live catalog:

• Structured Feed Ingestion: We monitor partner feeds and verified merchant announcements on a scheduled cadence with polite rate-limiting and source attribution.
• Fact-Based Offer Normalization: Offer descriptions are generated strictly from verified discount parameters (percentage off, fixed dollar amount, product scope, and expiration date) and checked against a 3-gram similarity gate.
• Shopper Feedback Demotion: Every card includes one-click checkout feedback buttons. Codes that receive repeated failure reports are automatically moved to our review queue.
• Automated Expiry Sweeps: Hourly sweeps archive expired codes immediately so active store pages remain fast and accurate.
