# Interpret the User Upload Summary Email

> [!NOTE]
> You will receive a summary email if you [create a static segment](/v1/docs/static-segments) by uploading a CSV file.

After your file is uploaded and processed, you will receive an upload summary email with an attachment detailing users or attributes that were not uploaded or that have conflicts.
