Certified mail In marketing campaign?

Does anyone have any experience with using certified mail in a marketing campaign? I'm thinking it almost certainly always be opened which should translate to a higher response rate. A little expensive, I know.

 Good point. When I get certified letter or package I open it up immediately, but admittedly with a little anxiety sometimes.
