When using dynamic tags in a Punchh notification campaign using the HTML template, the system will throw an error if they are not in valid format OR unsupported.
In step 2 of the campaign, the user will not be allowed to move forward if a broken or unsupported dynamic tag has been included in the HTML email template.
You will see an error much like this error seen below. In this example the tag does not include the underscore typically found in dynamic tags, so the error is thrown. Replacing the tag with {{{first_name}}} will allow the email to be validated and the campaign to move forward.
