I have a quick question for the copywriters here who have direct marketing experience in the "offline world".
Logically speaking, assuming a ceteris paribus condition (for the sake of simplicity), a 3 to 4 page sales letter mailed out to a targeted list should technically outperform a mailed out flyer in the same niche, right?
Assuming I'm not thoroughly mistaken, would any of you happen to know where I can dig up some statistics on this issue? I've tried Googling for days, but to no avail.
Also, I've stated a ceteris paribus condition for the sake of simplicity. But yes, I'm well aware of the dynamism that entails marketing in general. And that there are a plethora of intertwining factors all affecting each other at the same time.
Any assistance would be much appreciated!
