How Does NetSuite Email Case Capture Match Senders to Records?

NetSuite's email case capture mechanism automatically assigns customer and contact fields on a case by evaluating the sender's email address.If a direct match for the email address is not found, NetSuite defaults to an anonymous customer, which is configured within the support preferences.When multiple matches for an email address exist across different record types, NetSuite prioritizes the most specific match. For instance, a contact record is considered more specific than a child customer record, which in turn is more specific than a parent customer record. If the same email address is present on a parent customer, a child customer, and a contact associated with that child customer, the case will be linked to the child customer record and the specific contact.To associate multiple email addresses with a single customer for case capture purposes, additional contact records can be created and attached to that customer.It is important to note that NetSuite allows contact records to be linked to employee records, and a contact record can be created for each employee, enabling similar association for employee-related cases.In situations where conflicting email addresses are found across multiple customer records, NetSuite will set the customer field to the anonymous customer and will not populate the contact field.Similarly, if an email address belongs to a standalone contact not directly linked to a customer, NetSuite will set the customer field to the anonymous customer and will not set the contact field. Independent contacts with an email address that are not associated with a customer will not be linked to cases.
