JMO but I would stick with a standard PFD letter. I personally would not want to document any sort of agreement that may have been recorded, implied or otherwise. As mentioned, let them put the acceptance on their own letterhead. Also, the last line can very well get you into trouble. Though you can allude to it, you cannot tell them that they will only get paid if they delete. It's illegal. Just dropping the 'Only' fixes that.
