Add compatability with The Newsletter Plugin

I use The Newsletter Plugin to create and distribute weekly "New Release" newsletters. Unfortunately when I try to add product variations using the product IDs nothing is displayed, and trying to show the parent product also doesn't work as it is hidden. Being able to show the single variations shown onsite with the Show Single Variations plugin in a newsletter, would be awesome. If anyone knows of a newsletter plugin that is already compatible with Show Single Variations please add a comment, if there are no known compatible newsletter plugins then adding compatibility would be amazing!
