Subscription boxes have crossed the chasm. What seems like just a few months ago, Gen Z consumers began flocking to services that deliver ready-to-cook meals, fashionable wardrobe updates, and a month’s supply of pet food to their doorsteps on a day or two’s notice. And again next month, and the month after that.

It’s perhaps the most common conversation I have with prospective clients, and it goes something like this: Tim, I really need to communicate with potential new customers, but I don’t have a database list to send to. Where’s the best place to buy a list? Oh, and by the way, I need it fast and I don’t have much budget to work with.

As I interrupt the question, I respond that there is no place to safely buy/rent/gather/assemble a safe email list at any price. A look of despair ensues. 

Huh?

I repeat: There is no place to safely buy/rent/gather/assemble an email list at any price.

Early in my career, I had a boss named Audrey who was famous for saying, “If you didn’t measure it, it didn’t happen.”

As marketers, measuring and tracking key performance indicators (KPIs) is in our DNA. It's easy to see why, because we're continually asked to prove our worth: "Show me the spend, show me the time, show me the value."
