Listing Feed for Email

I love your plug-in, it works great. I use Constant Contact and want to sent a few of my listings out to my email database on a monthly basis. In Constant Contact I can add blog posts by searching my feed, but I can’t for the life of me figure out what the feed would be for the listings. I tried http://foldetta.com/listings/feed/ http://foldetta.com/listings/feed/rss/ can you offer any suggestions?

Thanks
