Catch shoppers reusing your one-time discount under a new email — audit included.
DupeGuard stops customers from exploiting your discounts — it doesn't manage the discounts you create. Install it and it scans your recent orders for free, then shows a dollar figure: how much of your one-time discount went to the same shopper under a different email. It looks past the email address — Gmail aliases, disposable inboxes, repeat phone numbers — and links accounts that are one person. Every flag comes with a plain-language reason. Monitor, flag, or block: you choose.
- Audit of your recent orders - see what discount abuse already cost you
- Links one shopper's accounts by email alias or repeat phone number
- Every flag explained in plain language with the evidence behind it
- Roommates stay safe - a shared address alone never links two accounts
- Choose monitor, flag or block - auto-cancel is always opt-in
