If you’ve ever struggled to write a compelling sales letter, ad, or email, the problem might not be what you’re saying. It might be that you’re saying too much.
Michael Masterson, the legendary direct-response copywriter, spent two decades writing copy before he stumbled onto what he calls the “Rule of One.” The discovery came after analyzing reader ratings for his Early to Rise essays. The highest-performing pieces all shared one trait: they presented a single, focused idea.
Not two ideas. Not five tips. One.
Masterson went back through his collection of the greatest promotions ever written. About 90% began by hitting one idea hard. Victor Schwab’s famous “Top 100 Headlines” from 1941? Same pattern. Headlines like “How I Improved My Memory in One Evening” and “The Secret of Making People Like You” each delivered one clear, instantly graspable promise.
The principle extends beyond copywriting. Masterson applied it to meetings (one goal per meeting), networking (one key person to connect with), and product development. The focus sharpens everything.
What the Rule of One Actually Means
The Rule of One isn’t just about having one idea. It’s about constructing an entire piece around five unified elements:
- One good idea the reader grasps immediately
- One core emotion that drives the response
- One captivating story that validates the promise
- One desirable benefit the reader wants
- One inevitable response that feels natural
Bob Bly demonstrated this in a 200-word email that generated over $20,000 in sales. The idea: e-books are the easiest product to create and sell online. The emotion: “This is simple. I can do this.” The story: Bly invested $175 and made $20,727. The response: click here now.
The Tossed Salad Mistake
Most copywriters break this rule instinctively. They gather a list of features and benefits, then cram as many as possible into the promotion. The logic seems sound: if one benefit doesn’t connect, another one will.
Masterson calls this the “tossed salad” approach. Throw everything in and hope something sticks. It’s the default recipe for mediocre copy.
The problem is that multiple ideas compete with each other. They pull attention in different directions and dilute emotional power. A promotion with six selling points often converts worse than one with a single, well-supported claim.
Think about the taglines you actually remember. “You deserve a break today.” “Think Different.” “We try harder.” Each one captures a single idea. You never see “You deserve a break today, and you’re lovin’ it” because that would weaken both messages.
Porter Stansberry built two multi-million-dollar promotions around this exact principle. Each highlighted one dominant investing idea. Not several. One.
The challenge is finding that one idea that’s strong enough to carry an entire promotion. It has to be easy to understand and easy to believe. Once you have it, your job is to support it with stories, facts, and proof. But everything points back to that single, compelling core.
The Freelance Copywriter’s Playbook: Getting Clients When You’re Just Starting Out
Breaking into freelance copywriting feels like a catch-22. Clients want experience. You need clients to get experience. Bob Bly, who has spent decades building a six-figure copywriting practice, offers a different perspective: results come from activity, not credentials.
His advice to nervous beginners is blunt. It doesn’t matter if you feel confident. It doesn’t matter if you’re enthusiastic. If you call ten prospects a day or send ten sales letters a day, you will get work. Period.
The Three Types of Clients
Bly breaks down the market into thirds. One-third of clients will only hire writers with exact experience in their industry. Another third wants someone in the ballpark. The final third doesn’t care about your background as long as you can write.
New copywriters should focus on that last group. Once you have samples from a flexible client, you can approach the more demanding ones with proof you understand their space.
Building a Portfolio from Nothing
The sample question haunts every beginner. Bly’s solutions are practical:
- Rewrite existing ads to make them stronger and use those as samples
- Do pro bono work for nonprofits
- Offer free projects to friends’ businesses in exchange for printed samples and testimonials
- Target small local businesses willing to take a chance on a new writer
- Use polished assignments from copywriting courses if they’re genuinely strong
When a prospect asks for samples you don’t have, Bly suggests a different approach: “Send me your current piece. I’ll do a free critique. If you like it, hire me to write a new one. Only pay if it beats your control.”
That offer flips the risk. The client has almost nothing to lose.
The Economics of Getting Started
Starting a copywriting business requires some investment, but not much. Bly estimates you should spend about 5% of your first-year income goal on marketing. If you’re targeting $50,000, that’s $2,500 for the year.
If you’re not willing to spend $148 on a mailing, you won’t succeed. The math works in your favor. A hundred letters costs less than $100 to send. If one person hires you for a $1,000 project, your return on investment is 10:1.
The key is keeping the pipeline full. Figure out how much marketing generates the work you want, then do twice that amount. When you finish one assignment, the next one should already be waiting.
Pricing Your Copywriting Services: What to Charge and How to Raise Rates
Setting fees as a freelance copywriter involves more guesswork than most people admit. Bob Bly, who has worked with major direct marketers for decades, offers concrete benchmarks while acknowledging the wide variation across markets.
You can charge by the word (50 cents to $1), by the hour ($50 to $200), or by the project. Most direct-response copywriters prefer project fees because they reward efficiency. As you gain experience, you get paid twice as much while the work takes half the time.
Sample Fee Ranges
Bly’s personal rate card provides useful anchors:
- Sales letter: $2,000 to $5,000+
- Direct-mail package (lead generation): $3,000 to $5,500
- Direct-mail package (mail order): $3,000 to $15,000
- E-mail promo: $2,000 to $2,500
- Landing page: $950 to $2,500
- Website home page: $1,500
- Additional website pages: $750/page
- White paper: $1.50/word
The spread is enormous because context matters. Copywriters serving small local clients charge near the low end. Those working with major national accounts can command premium rates.
The Rate-Raising Conversation
If you’ve underpriced yourself with an existing client, the conversation is uncomfortable but manageable. Bly’s script:
“I’ve raised my rates. You paid $500. This type of project is now $1,000. But for you, I’ll offer a discounted rate of $750 for the rest of this year. Starting January 1, it becomes the full $1,000.”
Clients understand that prices increase. Meeting them halfway softens the transition. They may even appreciate the break you’re giving them at 25% below your list price.
The Royalty Question
Major direct marketers sometimes pay royalties on top of flat fees. The most common structure is a mailing fee of 1 to 4 cents per piece mailed after the initial test. A rollout of 1 million packages at 2 cents per piece generates $20,000 in royalties.
Some clients pay a flat bonus if your letter becomes the control, often double your original fee. Very few pay royalties based on actual sales or profits, and those arrangements require careful tracking to ensure you actually get paid.
The copywriter who makes money for clients can write her own ticket. That’s the single most important insight from Bly’s career. Beat controls, create winning offers, suggest profitable strategy. Everything else follows.
