That depends on how your email is set up. But eventually you will have to go through your HTML code and search for that field name. If your email doesn't have dynamic content, you can just hit "Edit Code". If it does, you will need to go through all segments.
Got it, yes I already searched all the HTML code and didn't see any reference to that token. At this point we will probably just resort to deleting the email entirely so we can continue with our clean up. Thanks
