How do I track my Certified Mail using CML?

To track your Certified Mail in your Certified Mail Labels account, log in, and navigate to Reports -->  Summary Tracking Report

Here you can filter your search based on the search criteria fields OR you can just click the blue Search button to bring up all of your USPS Tracking data.  

All the tracking data along with PDF Signature reports are updated in your account daily.  However, you can always get the latest tracking by clicking the "Update & Create Report" button in the details of a specific record or by selecting multiple records and clicking the "Update & Create Report" button.
