Email Verification

Email Verification enables you to assess the risk of email addresses provided by the end user. It is a fundamental risk check that analyzes an email address to provide an overall risk. It, adds email intelligence as a layer of defense to fraud prevention. It assesses risks by evaluating email address metadata points such as domain details, email details, and risk indicators.

Use Case

For those with onboarding and account login workflows, who wish to understand and assess the risks of a given email address.

Supported Credentials

To use Prepared Data with email verification as a standalone capability use workflow key 10066

Key	Type	Mandatory	Description
Email address	String	yes	Email Address of Applicant
ipAddress	String	no	The IP address entered as a string. Either IPv4 or IPv6 format is accepted.
