How much control do I have in controlling what advertisers are in my insert program?

Absolute control. Every advertiser that places an insert into a program will be approved by you first.

Even prior to considering an order for placement, Stanton Direct will submit a "clearance" that outlines who the advertiser is, the rate they are requesting and a sample of their insert. As the program owner, you reserve the right to decline any proposed advertiser for any reason.
