Why is my imported segment much smaller than the original user list in my CSV file?

When you import a list of users from a CSV file to create a segment, our system matches each user in the file against the existing user profiles in your application. This matching is done using a unique identifier, such as a UserID or email address.

A discrepancy in the user count almost always means that some identifiers in your CSV file do not correspond to any existing user profiles in your Pushwoosh application. The system correctly skips these unrecognized users during the import process, as they cannot be added to the segment.

Common Reasons for Discrepancy:

• Mismatched Identifiers: The user identifier in your source system (e.g., your backend or analytics platform) is different from the UserID registered in Pushwoosh.
• User Not Registered: The users listed in your file were never registered in your Pushwoosh application, so no profile exists for them.
• Outdated Data: The CSV file contains data for users who have since been deleted from Pushwoosh.

How to Troubleshoot:

1. Verify Identifiers: Confirm that the user identifiers in your CSV file are the exact same ones being set as the primary UserID in your Pushwoosh application.
2. Check Data Source: Ensure your data export process from the source system is accurate and provides up-to-date user information.
