But not standard postcards or mass mailers.
An example: I worked for an apparel company selling custom apparel (shirts and hoodies mostly) to army Battalions/Companies/Platoons…
We managed to grab 28% market share of an army base for $150.00 by sending a sales letter with a knock out offer and a Rubik’s cube (there were actually two rounds of mailers but the total of both of them was $150)
Had the company’s supply chain not imploded it should’ve brought as much as $300,000 in gross profits of the course of the year. I’d say a 2000x ROI is not bad for a week of work and a couple hundred dollars in materials.
I think lumpy mailers à la The Ultimate Sales Machine by Chet Holmes are a phenomenal way to cut through the clutter with CPM‘s skyrocketing and conversion rates plummeting for PPC marketing.
