Restoring a Branded Tracking Link Domain Back to the Marketo Default

[#1]

Issue

You have a CNAME for your Branded Tracking Links in email but want to restore the settings to the system default (example: mkto-ab01234.com).

Solution

Once you have set up a Branded Tracking Link domain, it is not possible to restore it to the Marketo default.  You can change it to a different CNAME domain, but it is not possible to revert to the original.
