If I had the certification, I would add CDMP to my email signature. Looking on Linked-in there are 566 people who list it and about 50 job positions listed in the last month that also have CDMP certification preferred. Monster.com too lists 68 positions with preference to CDMP. So it looks like it is gaining traction. See the screenshots attached.

I do :D. If nothing else, its a conversation starter. Also, you work hard (and pay) to get it, so why not promote that you have it.
