Upload history lets you track the status of your recently uploaded lists, such as a contact list, a statics segment, or any of the suppression pages.
To find the uploaded lists, navigate to Components > Upload History.
How does the Upload History work?
The Upload History option allows you to track down the latest uploads from the listing page. The Upload History page is populated with lists from the contact list page or static segment pages. 
On the listing page, you can find the following information:
- Status: Status depicts what is the current situation of the uploaded list. It can be any one of the following:
- Uploaded: Your list has been successfully uploaded.
- Uploading: Your list upload is in progress
- Failed: Your list upload didn't happen. Retry the uploading in such a case, or look at the error report to find the possible reason.
- Name: It displays the name of the CSV or XLS file uploaded, along with the name of the list.
- Data Types: This defines the type of page uploaded as a list. Possible values are Contacts for contact lists, Suppressions for global unsubscribe, unsubscribe group, and bounce pages, and Segments for static segment pages.
- Uploaded On: This displays the time of the upload. The data shown here is in the UTC time zone.
