How to Write an Effective Sales Letter for Your Business

Is your sales letter a killer? Or is it killing your business? Find out what makes a good sales letter and read the latest sales letter makeover by Ernest Nicastro.

It’s the middle of the night and your phone rings. You pick it up and mumble a half-asleep hello. It’s your brother-in-law, Bob, who owns a small business. “Look,” he says, “I’m sorry to be calling you so late but I’m looking at our month-end numbers and they are terrible. Truth is, they’ve been in the tank for the last several months. And, well, we need to do something quick to generate leads and sales. So I was wondering if you could write a good sales letter for us?”

Now here’s the question: Which of the following two responses would you be most likely to give brother-in-law Bob?

  • “Sure I can Bob. I’ll have a killer sales letter ready for you in the next 24 hours. Now go to bed and stop worrying.”
  • “Bob you know I’m always happy to help. But sales letters aren’t my area of expertise. If it’s this important to you, what you need is a good copywriter. Someone who does this type of thing for a living — and is darn good at it.”

My point is this: Unless you chose response number one, and did so with the heartfelt conviction and steely confidence that you can write Bob a compelling sales letter that will quickly turn things around for him…you probably shouldn’t be writing your own sales letter. That said, we all know that thousands of small business owners — for better or worse — choose to be their own copywriter.

In the “better” department are those business owners who invest a substantial amount of time, effort and money in becoming very good copywriters. In most cases these are people who have a passion for marketing and writing. And many of them go on to build highly successful companies.

In the “worse” department are those folks who, while very smart and very competent in other areas, don’t understand that their intelligence and expertise don’t carry over to marketing and copywriting. In short, these very smart, very competent people aren’t smart enough to get out of their own way. Nor are they likely to be the types to put a lot of time and effort into educating themselves about the art and craft of writing effective sales copy. “After all,” these very smart people think, “how hard can it be?” As a result, their businesses aren’t nearly as successful as they could or should be.

OK, now that I’ve covered “better” and “worse” let me address everybody else. Everybody else is the vast majority of small business owners who choose to be their own copywriters. They aren’t as good as the best and they aren’t as bad as the worst. But they could be a lot better. If they worked harder at it.

How much time and effort are you willing and able to invest?

My pointed observation from reviewing hundreds, if not thousands of self-penned sales letters from small business owners is this: A majority of these otherwise by and large hard-working and conscientious people…don’t put nearly enough time and effort into doing what is required…in order to write effective sales copy. Maybe they don’t have the time or they haven’t divined a good process. Most likely it’s a combination.

Well, I can’t give you more time. Whether your name is Bill Gates or Bill Bailey we all get just 24 hours every day. But I can help you with the process. For the sake of illustration what follows pertains to sales letters. That said, most of the tips are applicable to any type of sales copy.

For the business owner who chooses to write their own sales letter: A proven process for writing effective copy. 

1. Document your knowledge of, and experiences and interactions with your customers – Think about your best customers, the 20% in Pareto’s 80/20 rule. Compile a collective psychographic and demographic profile of them. Age range, education, predominant personality type, job title (if you’re a B-to-B marketer), income, political views, the magazines they read, the books they read, all of this and more should be in your written profile. You’ll also want to review responses to your customer satisfaction surveys and study your “white mail.”

Most importantly, you should list and rank the key motivators that drive your customers’ purchasing decisions. In most cases, it will be one or more of the following: Fear, exclusivity, greed, guilt, ego-gratification, salvation and anger. And finally, if you have a sales staff involve them in this process as well. Their help and input can be invaluable.

When it’s all said and done you’ll have a good understanding of who your best prospect is, and what likely goes on in their mind when considering the purchase of a product or service in your category.

2. Study the work of successful copywriters and their sales letters – Alexander Hamilton wrote, “All the genius I have lies in this; when I have a subject in hand, I study it profoundly.” One of the most effective ways to learn anything is by studying how the most successful people in a given field do what they do. Fortunately, we live in an age when all you need to study great sales letter copywriting is a connection to the Internet.

For example, Google the phrase “greatest sales letters” and with just a couple of clicks, you’ll be able to download a free PDF containing the complete text of 5 of the most successful sales letters ever written. Included in the file is the famous “Two Young Men” sales letter for the Wall Street Journal. Conservative estimates are that this one letter generated over a billion dollars in revenue, making it arguably the most successful single piece of advertising in history.

Of course, the Internet isn’t the only place to find successful sales letters. Some of them will come directly to you in your mailbox. That’s why, if you write your own copy and seriously aspire to be better at it, you shouldn’t automatically toss any mail not of immediate interest to you. Give all of it a quick look and save those few pieces that grab and hold your attention. Make a “swipe file,” and when writing your own letter pull out that file and look through it for copy and techniques you can swipe and use.

In addition, there are several sales letter compilation books, each of which constitutes a huge swipe file in and of itself. Because all of these books include word-for-word reproductions of some of the most profitable direct mail packages ever created. In most cases, they also include expert commentary from the copywriters and designers who worked on those packages. Three such books that I have found to be of great value are –

  • Million Dollar Mailings by Denison Hatch.
  • World’s Greatest Direct Mail Sales Letters by Herschell Gordon Lewis & Carol Nelson.
  • The Greatest Direct Mail Sales Letters of all Time by Richard S. Hodgson.

Another good book to have in your library is a compilation of letters from a single writer, The Robert Collier Letter Book. Originally published in 1937 this book is a timeless classic of highly effective sales letters by an all-time great copywriter. Better yet, almost all of these letters can be easily adapted for use today.

Finally, if you want to study very recent successful direct mail efforts pay attention to those direct mail pieces that turn up in your mailbox multiple times. The fact that you’re getting a letter a second or third time means that it’s a proven money-maker. In addition, you may want to subscribe to Who’s Mailing What! Who’s Mailing What! maintains the world’s largest library of direct mail, archiving information on over 130,000 packages in nearly 200 categories. And it’s all searchable by any number of parameters.

How to get the most benefit from your study
It’s not enough to simply read a letter or two a few times and think you have the hang of it. To maximize the benefit from your study I recommend that you pick a proven response-producing letter and, at a minimum, do the following:

a. Read the letter a minimum of five times, preferably once a day over a five day period. Pay attention to every word, every sentence. Why did the writer use that word, that phrasing? Make note of the transitions from one thought to the next, note how the copy is all about the reader and not the product or service. Note the motivational buttons being pushed and how the writer pushes them. This intense study and repetitive reading will help the copy embed itself into your conscious and subconscious mind.

b. Do the same thing, but read the letter out loud. Why? Because people read with their ears as well as their eyes. By reading the letter out loud you’ll get a better sense of the rhythm and flow of the copy and how it sounds to the person reading it.

c. Sit down and write the letter out by hand at least once. Again, by doing this you’ll get a better feel for every little nuance of the letter. Because the copywriter chose every word and placed every comma, colon, dash, ellipsis and period where she did for a specific reason.

So, to sum things up. If you’re a business owner who chooses to be your own copywriter and you expect your sales letter to have a snowball’s chance of success, you should, at a minimum (1) Get a good handle on who your best prospects are, how they think, and what motivates them when considering a purchase in your category (2) Profoundly study successful sales letters by engaging in visual, auditory and kinesthetic learning behavior. I repeat, this is the minimum you need to do before you’ll be ready to commence with your first draft.

When you’re done with draft number one, print it out (to see how it looks on paper), read it over several times (at least once out loud), stick it in a drawer, and forget about it for a couple of days. Then pull it out again and look at it with “fresh eyes.” Things will jump out at you that you’ll want to edit and your edits will make your copy stronger. Print out the revised version, read it over several times, stick it in your drawer, come back to it again in a couple of days. Repeat the process. Then, after a few more rounds of revisions, you may finally have a letter suitable for mailing.

Now if all this sounds like a lot of work — well, uh, it is. But if you’re going to be your own copywriter, and copywriting isn’t your core competency or a natural strength, to think that you can just sit down at the keyboard and bang out an effective sales letter, or for that matter, any type of sales copy, is foolish. You are doing yourself, your business and your employees an extreme disservice.

OK. Let’s take a look now at the following sales letter to see how it can be improved.

Black = Original letter copy.
= Ernest’s critique/commentary 
= Ernest’s suggested copy

Quite frankly, 80% of all businesses fail in the first five years …A pretty well-known fact that doesn’t shock anyone anymore. And what’s the deal with quite frankly?

And, 80% of the businesses that make it to 5 years will fail by the 10th year.

Do you know the number one reason businesses fail? This would have been a better starter for the headline than what the writer chose. Questions, good questions, are engaging. And this one, targeted at a business owner, has some stopping power.

Answer: The business owner’s strengths at one stage of growth become company crippling weaknesses in a new stage of growth. I dislike this “answer” for two reasons. First, without citing a respected source, the answer isn’t believable. Second, the copy has an esoteric, high-level ring to it — like something you would hear in an MBA class.

Could this happen to you? I’d revamp this headline entirely. Based on a trip to this company’s website, I’d go with something like this: Now — in just three hours — you can gain the four most powerful sales-multiplying, profit-boosting secrets we’ve uncovered during a lifetime of work helping companies grow. What’s more, we guarantee you’ll be able to put this new knowledge and know-how to work immediately — on your own — or we’ll gladly refund your investment. Coming up with a great headline typically takes several hours and my suggested headline is far from great. But it’s an improvement.

Dear Business Owner,

Why not guarantee your company’s success by taking three hours to attend – with a select group of Colorado Springs business owners – the workshop: There is nothing attention-grabbing, thought-provoking or motivating about this opening. And the use of the word guarantee is meaningless. Here’s a suggested opening. Which, by the way, I swiped from a letter I found on the Internet: Have you ever questioned, as I have, what makes a business either a success or a failure? Hint – it isn’t what you think. Then from this point the writer can segue into pitching the workshop.

Turn Your Growing Business Into A Great Business Titles for workshops and seminars are all-important and this one is just so-so. But with a couple of tweaks it could be vastly improved. As in, How To Turn Your Growing Business Into A Great Business: It’s Easier And More Difficult Than You Think

NOTE: A guarantee is worthless unless you back it up. This one, while it may sound good, means nothing. It’s just another claim.

What separates the business owners who excel from those that struggle? How can we make this sub-head a more intriguing? How about this: What separates those business owners who are raking in the profits from those that are just getting by? Interestingly enough, very little. But that little bit makes a huge difference.

Our research at Origin Institute – the leading provider of consulting, training and research for growing businesses Who, besides you, says so? The phrase, the leading provider of, is bandied about by so many companies in the same meaningless way there should be a law against it unless you can prove it.– has shown successful CEO’s step, not stumble, in the same growth direction Is it just me or is there anyone else out there who doesn’t have a clue as to what the terms growth direction or profit design (see below) mean? Look, don’t get me wrong. I have no doubt that the principals of this company are smart, savvy, experienced business consultants that can do a lot of good for a lot of businesses. So maybe when they’re sitting in front of a prospect or even talking with them over the phone they can make terms like growth direction and profit design energize and motivate people. But to paraphrase the great copywriter Herschell Gordon Lewis, in direct mail marketing clarity is paramount. as their company – at the right time. There’s no logical progression of thought connecting these two sentences. No matter which of the 7 growth stages your company is in – it’s the CEO’s leadership that determines success, or failure. There’s nothing motivating or interesting in these two sentences. How about we try something like this, with additional information drawn from the company’s web site: Drawing on over thirty years of multi-faceted, hands-on experience guiding and helping grow more than 600 companies…Origin Institute principals have identified and documented 7 distinct stages of growth.

I am happy to announce my profits are up 25%. Thanks for a great seminar; a great value.”  Beth Clark, CEO, Clark Insulation, Cleveland, OH Excellent. A meaningful, specific testimonial. But it should have been presented much earlier in the letter. How about on page one? For example, we make our opening line of text read, What if you could boost profits by 25%? This business owner did. Then we double space and present this quote.

Summary: In 1984 Wendy’s Hamburgers ran a series of TV commercials featuring elderly actress Clara Peller. In these ads a tiny hamburger patty sits atop a huge bun. As many readers will recall, Clara would look down at the patty and say the catch phrase, “Where’s the beef?” That’s what I found myself thinking as I read this letter. It needs a lot more beef, as in meaningful, meaty, specific and clearly stated, easily understood benefits.
