Promo and bonus abuse prevention that keeps offers for real customers.

Promo abuse, also called bonus abuse, is when the same people claim welcome bonuses, referral rewards or first-order discounts again and again, under new names, emails and phone numbers. Each account looks like a new customer, so the offer pays out every time.

Monnai reads how each email and phone number behaves across its network: when it was first seen, how often it is used, sudden bursts of activity and how many identities share it. Accounts that look clean on their own show what they have in common.

They cost nothing, so abusers use a fresh one for every sign-up. Monnai tells you how old an email or a number is, flags throwaway numbers, and checks each email domain against its own global list of throwaway domains, including brand-new ones.

Blocking every new account kills the campaign along with the fraud. Monnai reads good signals as well as red flags, such as an email address or a number used steadily for years, so real customers get the offer instantly while the farms are declined.

Yes. Send the sign-ups from a past campaign, flagging the abusers you already know about if you want the uplift measured. Monnai scores them offline, with no integration on your side, and your full report arrives within 5 business days.
