Opportunity Seekers

Has anyone had any luck with selecting a mailing list for opp seekers? Would you be willing to share the name of the source/broker?

I've had some good luck in the past and some bad luck. I seem to have decent sales as long as I can get my campaign delivered. My experience has shown some of these opp seeker lists are nothing but nixies. Nothing like getting a mail box full of undeliverables

Thanks, Matt
