Yea, not sure if it applies to your situation, but we have a special notifications list, retail special notifications list, report notifications list, some emails are sent just as a response to a report request, etc... So every email that we send, we have to make sure that the sentence in our unsubscribe section corresponds to the type of email that we're sending. If this is baked into the template, it eliminates variations in text, but it also makes the templates much less flexible. As a token (or maybe a snippet), they are much more flexible.
