When you add an email template mask such as #RatingLinks#, #WhatHappened#, #URL#, or #Category#, you may encounter situations where it does not function as expected.
One common reason for this issue is that the HTML of the email template may be malformed. To troubleshoot further, we recommend checking for any hidden symbols or formatting problems. You can do this by switching to the source code HTML view in the template editor. Simply click the "</>" button to access the source code and carefully review the markup for any irregularities.
If you come across a strange link formatted like this:
<!--this might not work-->
<a href="{some_broken_code}#URL#">#URL#</a>
You will need to correct it. The most effective solution is to remove the link tag altogether and retain only the #URL# part.
