troyintn,
Similar situation here. Under my company's CDP, I get zero marketing materials. So, I never receive any special offers or free rental coupons. I sent an email to hertz asking them to change my default CDP associated with your #1 GOLD account to something other than my employer. It can be AAA, United, Marriott etc. Once that is done, I receive marketing material from Hertz.
When I make a reservation, I select my employer's CDP for the rate so that I still get LDW and he corp rate but now I also get my free rental coupons.
