Email Risk Data

Email risk data includes:

These data points will only be returned when you pass the email address as an input to the minFraud Insights and Factors web services. Learn more about passing inputs to minFraud.

If you're using email risk data for manual review, and you use the minFraud Factors service, you may also find it helpful to consult the email risk factor scores to give you a better picture of the transaction. Learn more about email risk scores.

Email reputation flagging

If an email address engages in risky activity anywhere across the minFraud Network, we flag it as a high risk email address.

High risk email flagging is displayed as "Carder email" under Email and Device ID Checks in the transaction review screen in the account portal. Learn how to review transactions using the account portal.

Email and domain first seen

The minFraud service retains a record of when an email address or email domain was first seen on the minFraud Network. The minFraud services have been recording when an email address was first seen since 2008, and when an email domain was first seen since 2019.

An email address that has been conducting transactions for a long time across the minFraud Network may be more trustworthy than a new email address. If the email has been around longer, this may also mean that our assessment of whether the email is a high risk email address is more accurate.

The minFraud services also track how long we've seen a particular email domain (for example, gmail.com, hotmail.com, etc.). Customers with email address domains that have only recently been seen may not conduct many transactions, or the domain could be new. Alternatively, this could indicate a fraudster creating a new email domain to fake being a legitimate business or to avoid having a history of use.

Free and disposable email detection

We flag free and disposable email domains. Use of free email providers (e.g. Gmail, Yahoo, Outlook, etc.) by consumers is the norm, so this data point is often useful only in business-to-business contexts where you expect transactions to be conducted using a business email domain.

Disposable or temporary email addresses are sometimes used for privacy or to prevent spam, but they can also be used by fraudsters to avoid detection, because there is no history of use to draw from to inform risk scoring.
