About
Hi, I’m Kevin Donlin, the man behind Client Cloning Systems.
Since 1998, my team and I have helped more than 1,270 entrepreneurs and business owners get more clients like their best clients.
But who am I?
Here's what clients say:
- "Kevin Donlin creates high-converting sales letters, emails, and marketing campaigns that generate millions in revenue."
- "He helps businesses grow faster, increase sales pipelines, and uncover hidden profits."
- "He delivers measurable results -- whether it's tripling revenue, closing six-figure deals, or automating sales."
- "On top of that, he's a trusted advisor on marketing and strategy."
(That's all my client success stories, summarized.)
I've been in marketing since 1994. And in my experience, the only way to survive -- and thrive -- is to embrace change:
- digital marketing pioneer in 1994, when I sold the first job-search ebook, "How to Find a Job on the Internet" on Usenet (there was no Web) for $10 (payable by check sent by U.S. Mail)
- Webmaster for FedEx.com from 1995 to 1998, processing all email inquiries worldwide (some in German)
- among the first to use pay-per-click (PPC) advertising in 1999, when I ran ads on Goto.com
- author of the books Voice of the Buyer Marketing, 21 Quick Ways to Get More Clients, and Marketing Multipliers
- interviewed on marketing by Fox 9 News, ABC-TV Detroit, NBC-TV, CBS Radio, The Wall Street Journal, The New York Times, Fortune magazine, Entrepreneur magazine, and many other media
- featured by Dan Kennedy in his book, No BS Brand-Building By Direct Response, with two of my sales letters
Bottom line: I'm agile and adaptable, trusted by clients in times of rapid change and uncertainty. From the birth of E-commerce in 1994 to AI in 2024 ... and beyond.

Interviewed live on Fox 9 News, Minneapolis-St. Paul. (I no longer look like a bomb scientist.)

Interviewed live on ABC-TV Detroit. (I no longer look like Sigmund Freud.)

I run obstacle course races, like the 31-mile Spartan Ultra in Dallas (2022).
Why should you care about all this?
You can trust me to understand your clients and your business because I’ve been inside dozens of businesses. I've been a baseball groundskeeper, cashier, dishwasher, English teacher, guitar player, landscaper, newspaper columnist, paper boy, record store manager, resume writer, songwriter, textbook writer, track coach, warehouse worker, and webmaster, among others. I can make a connection with almost anyone.
You can trust me to learn the language of your market because I’ve learned German, Greek, Irish, Japanese, Latin, Russian, and Spanish. I can talk to almost anyone about almost anything.
When you work with me, you work with a pro who "gets" client service, not some temperamental flake. That’s because I lived and worked in Japan for 2.5 years, where the customer is not king -- the customer is GOD.
You benefit from my lifelong LOVE of learning, which keeps me up-to-date on marketing. That’s because I was a National Merit Scholar at Michigan State University and have since invested over $200,000 in seminars and courses.
You benefit from my competitive nature. I run Spartan obstacle course races at age 60. Next up in 2026 are the Spartan Beasts in New Jersey, Vermont, and South Carolina.
Now, before you go ...
