One of the best companies to come along in a long time that will help your mail stand out is http://www.3dmailresults.com/ 

The use of objects that make your direct mail "Bulky" will increase your chances by 300% of hitting your client's "A Mail" pile instead of file thirteen.

I highly recommend this company and use them quite often for my jewelry/gift store.  Take time to check them out...

Good Luck,
