A powerful marketing tactic: tell me exactly when I'm going to get it.
"This project will be done noon on Tuesday."
"You'll get the shipment at 4 pm."
Fedex has made billions shipping packages that didn't even have to be there fast, they merely needed to arrive at a time that we knew about in advance.
We don't want to hear, "up to 11 business days." We hope you care more about our project than that.
