Email insights is a collection of email address attributes that can be used in different configurations to assess risk with a specific email address. Since email addresses are used as a primary identity source in online transactions, evaluating the risk associated with an email address can assist in stopping fraud. These attributes are available to configure standalone, or in conjunction with other rules in the Agent Web Console (AWC).
Creating a Rule incorporating Email Insights
Note: The actions in this step apply to both the Auto Decision Engine (ADE) and the Auto Agent (AA) rules editors.
 Log in to the AWC.
 From the top navigation bar, click the Fraud Control tab, and then click Rules.
 Click Add Rule to open the Rules Editor.
 From the Rules Editor, click the Apply the following decision to the transaction when the conditions are met dropdown menu and select an action to be applied when the rule is triggered.
 Under Rule Conditions, expand Order, and then expand Email Insights.
 The attributes for Email Insights are split into two categories: Basic and Advanced. Expand your desired category, and then choose an attribute (a breakdown of each feature is provided below).
 In the Condition Editor, select an operator from the dropdown menu, and then in the text box enter your desired condition numeric value.
Note: All features in Email Insights use a numeric value (integer or floating decimal).  Under Rule Actions in the bottom left corner, next to Rule is , select or clear the Disabled checkbox (depending on whether or not you want the rule to be enabled), and then select or clear the Important checkbox (depending on whether you want to give this rule special preference in the hierarchy of rules).
 In the Rule Description field, enter a description for your rule.
 If desired, repeat these steps to add additional features to your rule, and then click Create Rule.
Email Insight Attribute Details
All Email Insight attributes are listed here with details about availability in the rules engine, category designation, data type (with range), starting suggestions, and definitions.
Note: Any rules listed as not available in the Rule Engine are available with Data on Demand.
