Understanding the Problem

When clients hit this issue, it is often due to a lack of visibility into the data flows coming into SFMC. This can be due to various factors such as incorrect data imports, misconfigured APIs, or incomplete data validation.

Investigating the Source

To investigate the source of these contacts, teams can start by reviewing the Contacts without Channel Address report, which can be found in the SFMC platform. However, as noted, this report does not include the source of the contacts.

Teams can then use various techniques to find the source of these contacts, such as analyzing data imports, reviewing API configurations, and checking data validation rules.

The root cause of this issue is often a lack of visibility into the data flows coming into SFMC, combined with incomplete data validation and incorrect data imports.

Best Practices for Preventing Junk Contacts

To prevent the creation of junk contacts without email addresses, teams can follow best practices such as validating data imports, configuring APIs correctly, and implementing robust data validation rules.
