On Ideas Direct Marketing. At On Ideas, Direct Marketing is treated as a distinct sub-discipline and staffed by gifted practitioners who love what they do and do it very, very well. With Direct we seize the opportunity to change minds through unsolicited communication with consumers or businesses; with messaging focused on driving success via a specific Call To Action. Flexible, tactile and as well-targeted as any Smart Bomb, Direct Marketing is part creative science, part scientific art. We and our clients benefit in both sales and market intelligence thanks to Direct Marketing’s unique emphasis on trackable, measurable results (known as “response”) regardless of the medium employed.
