Remove unsubscribe link from Newsletter

I simply want to remove the Unsubscribe link from my newsletter? Reason? I run a membership website on a different platform and have a separate database of members. Each time I want to send a newsletter I will just re-import my list of members. The unsubscribe link is not needed and actually gets in the way. There is no control over the unsubscribe email anyway. Please at least put in a tag to just turn the unsubscribe link part off.
