Resolving List Detective Issues in Salesforce Marketing Cloud

Share with

Understanding List Detective

List Detective is a feature in Salesforce Marketing Cloud that helps prevent email sending to role-based or reserved email addresses that are unlikely to be read by a human. While this feature can help prevent spam complaints, it can also block legitimate email addresses if not properly configured.

Root Cause of the Issue

The root cause of the issue is the recent update to List Detective, which added new role-based email usernames to the suppression list without announcement. This update caused many legitimate email addresses to be blocked, resulting in missed communications for the affected businesses.

Fixing the Issue

To fix the issue, teams running into this problem can follow these steps:

List Detective Inclusion Request

1. Identify the role-based email usernames that are being blocked by List Detective
2. Submit a request to Salesforce Support to include these email usernames in the allowed list
3. Wait for the request to be processed, which may take up to 3 days
4. Verify that the email addresses are no longer being blocked by List Detective

Heads up: Be sure to keep track of the email addresses that are being blocked and submit them for inclusion in a timely manner to minimize the disruption to your business.

Preventing Future Issues

To prevent similar issues in the future, teams can take the following steps:
