Edit an analytics tracking code
Several elements of your analytics tracking codes can be edited any time before they expire.
You can find your tracking code in the Analytics tab in your email project or in the Tracking code manager from the Analyze top menu option.
Select the Edit tracking code button in the upper right of the tracking code's summary view.
You can change the expiration date, the email type, and you can add tags. Custom parameters cannot be added or changed in an existing tracking code.
Select Update your tracking code in the lower right corner of the modal to save your changes. Your tracking code will update with the new information.
