Considerations When Uploading the First File to an Audience
When you're uploading the first file to an audience, you'll need to create a support case so we can make sure your file is imported correctly. Depending on the type of audience and your situation, you might need to do this before uploading your first file or after (or both).
When to Create a Support Case
Create a support case before uploading the first file in these situations:
For all audiences containing online data (mobile device IDs, cookies, etc.)
For audiences containing offline data (PII) when you want to change from the default settings (a different audience key than the identifier with the highest fill rate, a precision level other than household, an audience update method other than incremental update, or fields that are multi-value fields)
Create a support case after uploading the first file in these situations:
For all audiences containing offline data (PII)
