Chris Penn is the Director of Inbound Marketing at WhatCounts, a co-host of the Marketing Over Coffee podcast, and an active blogger at Awaken Your Superhero (christopherspenn.com). He frequency speaks on the intersection of marketing and technology. Most importantly, Penn does a lot of experimentation with email marketing;2 specifically, testing out new ways to grow his list and engage his subscribers. He also breaks the rules of email marketing—often. We talk more about him in Part III, “Breaking the Rules.”
Penn has been growing his email list since he sent his first newsletter in 2007. At the time of this writing, Penn’s list has grown to more than 13,000 subscribers.
“On average, it grows 68 percent (compound growth rate) per year, from an initial seed list of 1,000 to today. Some years have obviously been better than others,” Penn told us.
