I emailed the Chrysler incentive support group and they replied back:
In regards to your inquiry, Target-Direct-Mailers are provided to customers as random.
You currently do not have an active Target-Direct-Mailer in your name.
Please let us know if you have any further questions.

I replied back asking them to tell me how to do that or add me to a list.
Anyway this might help someone else...
