How Does Leaked Email Address Validation Work?

Upon searching with the Leaked Email Address Lookup tool above, IPQS will automatically lookup the email address against the country's number one collection of leaked data lists. A quick syntax check is performed to ensure the email address is properly formatted and then matched against our thousands of database lists. Once complete, the display will show if the email address was clean or if it was found, the details of which table and when it was first seen will be shown in that area.

Using these services in real time to verify potentially leaked email addresses is a great way to analyze user quality or perform lead scoring. This can be taken a step further for additional checks with leaked password validation and leaked username validation, for complete user verification.

What Leaked Email Address Lookup Data Is Available?

Using either the leaked email address verification API or bulk list processing will return whether the email address was found or not, if found, the name of the source list, and the date that email address was first seen on our lists. This makes it easy to identify a leaked email address that likely represent a fraudulent user with an compromised email address.
