Check this out. I got a direct mail piece from Google, offering me $100 coupon for AdSense. The poster child for the Internet and all things online and digital is using the old fashioned, dreadfully offline, less than 1% response rate channel of Direct Mail to drum up business. Oh, the irony.
One piece of feedback: I’d advise them to actually know the recipient’s name rather than addressing it to “Adsense Customer”.
