First, before knowing how to write a sales letter effectively. you must first have a clear knowledge of what a sales letter is.

All About A Sales Letter

A sales letter is a document intended to generate sales. It influences the reader to place an order, to request information about a product or service. The basic aim is to motivate the reader to take a specific action

This is a description of a real sales letter.

Results of my R&D

“I’m talking to you to inform you about the really terrific washing machine that I’ve developed. First of all, I know it’s wonderfully terrific because I spent years studying washing machines of all kinds. I then expanded my field of research and Development (R&D) to include all kinds of commercial washing machines, and I came to know about all the possible secrets of what makes dirt come out from the most inconceivable places. Now, TEN YEARS LATER, I’m ready to let you savour the fruits of all my hard work. I’ve developed the EZ WASHER.
I must tell you it will make all other washing machines you have ever seen pale in contrast.”

Do you find anything wrong with this sales letter? Almost everything is wrong.

The headline is all about the writer and does not speak to the customer. Also, it uses some technical terms. “R&D” for research and development. This is an industrial term, which may actually irritate some prospective customers.

We have no idea whatsoever what the 10 years of work refer to. Neither are we told about any exceptional features. The writer just generally raves about what great work he has done.

The sales letter talks about all what he has done in the last 10 years and not what I will get or at least what I can expect.

Before starting to write a sales letter, you must also try to put yourself in the prospective customer’s shoes. Realize how you treat unwanted letters that you receive. Most of these letters, if not all, go in the bin. In fact, you don’t even bother to open some of them.

Comparison Between Unsolicited Proposals, Brochures
And Sales Letters

Whether you are preparing a brochure or writing an unsolicited proposal, you can always make it better by realizing the similarities and differences between them.

A brochure is a record of your products and services. They are often produced on a large scale and given incognito. Brochures come in different kinds of shapes and sizes and are more often than not printed in bright colours with lots of graphics in it.

An unsolicited proposal is an article about your products and services. They are usually produced independently and given to someone precise (although it may be to someone you are not too familiar with). They are often in the form of a letter unless they are large documents, which are bound.

A sales letter is a short proposal and always aims towards making you take some action. Depending on the situation, sales letters may or may not be given to precise individuals and are sometimes sent to people you don’t know.

So what’s the dissimilarity?

It turns out that in reality there is not a lot of difference between them. All of them have to offer information and usually seek to influence.

Sometimes, the main intention of a brochure is to provide information. A key differentiator is whether the brochure should aim towards making you take some action.

Marketing materials are almost always fashioned to stimulate the reader to do something. It could be to visit their store, make a purchase, visit a website, or maybe just to place a telephone call.

If your brochure simply supplies information, you should reconsider it to make sure it is convincing, and consider re-designing it to induce people to take an action.

If you do have a call to action or something that you are trying to inspire the prospective customer to do, then it may help to imagine your brochure to be an unsolicited proposal.

The brochure should be intended to efficiently convince the reader to execute the call to action.
If you are writing a sales letter, you may not comprehend that it’s not much
different than a brochure asking the reader to take action. Try to focus on the aesthetics of the brochure.
Both brochures and unsolicited proposals are liable to suffer from not having too much information about the reader.

The more you are familiar with the reader, the more persuasive you can be. However, brochures and unsolicited proposals are frequently given to people who you are not too familiar with, usually in the anticipation of getting to know them better.

Segmentation, Targeting And Positioning

Preparing your sales letter means you need to really have a comprehensive
knowledge of the product or service being offered, the market dynamics, and the reader’s stated and unstated needs.

What does the product or service do for the one who requires it? How can the reader benefit from buying it? What is the unique selling point of the product or service?

To respond to these queries, you should begin by distinguishing the benefits from the features. The sales letter should be able to persuade your reader to buy your stuff based on the grounds of what benefit the product/service derives and not based on its features.

The benefit is what the product or service offers and what the consumer profits from the feature. A refrigerator, for example, has defrosting facilities (feature).

If that technology helps in getting rid of unwanted icicles and helps in keeping our greens fresh and healthy, then we have the benefit of that feature.

Decide on how you plan to advertise the product or service. Through the
Internet, direct mail, email, direct sales, print advertising, etc.? Is there some other advertising or literature to support the sales letter? Who is your
competition? What marketing activities have they undertaken? What is your advertising budget? Are you aiming too high? Who is your potential buyer? What stimulates a person to buy this item?

You have to be in the consumer’s position to realize whether your offer appeals to the readers’ emotional needs.

The Aida Model

Advertising copywriters follow the AIDA model. The AIDA model stands for
Attention, Interest, Desire, and Action.

Get Your Reader’s Attention

If you want your sales letter to have an impact on your readers, it must first get their attention. You can do this with a hard-hitting headline or lead paragraph that hits the nail directly on the head or you can even begin your letter with a captivating question. For instance, “Do you want to cut your electricity cost by 45%?”

An appropriate headline for a sales letter promoting a weight loss program might be: “Now, you can lose 15 pounds in 2 weeks without having to starve; and it’s easy and affordable!” This headline not only solves a problem but also offers a quick and easy solution that keeps in mind the price-sensitive consumer.

Gain Their Interest

You must clasp the reader’s interest by showing him why he needs your product or service. You have to create a want for your product or service. Let him know how his life will become easier with your product. Show him what he is missing by not even trying the product.

You can use testimonials or case histories. You can provide the communication details of users who have benefited from your product.

Create Desire

Now you’ve got the reader’s attention and hooked his interest. Next, you’ve got to create desire. Tell the reader how exactly he’ll benefit from your product.

Link the benefits to the reader’s daily life. Get him to realize how your product can benefit him, how convenient it is for him to get it, and how comfortable life will be for him afterwards.

Solicit Action

What do you want the reader to do next? Send in a reply card? Order the product or service? Call in asking for more information? Schedule an appointment? Notify him accordingly.

It is amazing how many sales letters do not inform the reader about the subsequent step. They consider that the reader is a mind reader.

But usually, this is not the case. You’ve worked hard so far. You’ve gotten his attention, hooked his interest, created desire. Isn’t it appropriate to ask for action? Don’t presume that your reader knows what to do next.

As a support to getting the preferred action, you must always incorporate a reply card with your letter.

The P.S. is one component of a letter that at all times gets read. Use your P.S.
to emphasize your most compelling benefit or restate your guarantee. Don’t
waste it on merriment. Used wisely, it could be the final prod that tilts the
buying decision in your favour. So be specific and give the final spurt.

Basic Elements Of A Sales Letter

What Are The Basic Parts Of A Sales Letter?

Any sales letter roughly follows the following sequence

  • Image.
  • Headline.
  • Greeting.
  • Lead paragraph.
  • Body.
  • Closing.

The Image:

If there is a logo or design for your business, use it in the sales letter only if it is really pertinent to what you are offering. You are not selling your business logo; you are selling benefits that the buyer will realize if he buys your product or service. Use a specific image that is inherent to your headline, content, and theme, or do not use one at all. Stick to words as far as possible.


The headline is usually 3 – 30 words long. It should be catchy. It should grab the reader’s attention and tell him what the ad (sales letter) is about. Ideally, the job of the headline is to get the reader’s concentration, target the viewers, list an advantage, and make an assurance.

Greeting And Lead Paragraph:

Any sales letter that influences the reader has the possibility of being opened and read.

  • Spin a yarn that the reader can identify with, using a conversational tone.
  • Announce a new product or service, an exclusive event, or important news, flaunting your unique selling proposition.
  • Speak to the reader as your equal: “Dear fellow car purchaser, are you aware of. . . “
  • You could start with something innovative, perhaps a quote or anecdote.
  • You could start by identifying the reader’s problem, one that your product promises to solve.
  • Ask a question that might excite the reader.
  • Let the reader in on some secret or uncommon information.

You could use a sub-headline to answer a query posed in the headline. For
example, Part A could say: “Want to lose 15 pounds within 3 weeks at an
affordable price?” Part 2 could say: “Well, this is how you can do it . . . “

Body Of The Letter:

The body copy should use the same tone and endure with the theme of the
headline. You should persist in highlighting the benefits and offer proof of the claim you made. Provide details of the benefits and the features. Build
credibility. Your basic objective is to create a need or want for your products or services and make people do what you want them to.

Closing Or Call To Action:

If you solicit the reader to order, support, or to contact you for the particular cause, you must make it easy for him to reply. You must support the sales letter with a prepaid envelope and an order form. If not suitable, supply a toll-free telephone number, an email link, and/or your URL. Always thank the reader for his patience. Always use a postscript.

A Final Suggestion:

Getting the reader to spend his hard-earned money on you is the real challenge.
The best way to ensure this is to use test readers. Test readers would be able to give their opinion if anything is missing in the letter.

How To Create An Effective Headlines

Every one of your marketing tools would require a headline. Headlines draw attention, make your message simple to read, get your key selling points across, and prompt your customer to buy the product and service.

Use headlines regularly in your sales letter to help people get your main message without having to grope about too much.

Headlines range from “hit-you-in-the face” to more understated ones that don’t appear like a headline at all.

Your headline gets noticed when it appeals to the reader’s interests. You must use your headline to point out difficulty the reader has or something you know the reader feels powerful about.

Seven Sure-Fire Headlines

  • Ask a Question. “Are you worried about becoming fat and flabby?” A question headline forces the reader to answer in her mind. You mechanically get the prospect involved in your message.
  • Begin your headline with “How to.” “How to lose 15 pounds in 3 weeks.” People love the information that illustrates how to do something valuable.
  • Provide a testimonial. The advice of a satisfied customer can act as a catalyst in pursuing others to buy from you.
  • Issue a command. Some traditional headlines order readers to “Aim High” and “Move Ahead” and so on. Turn your most significant benefit into a strong headline.
  • Significant news makes a good headline. This especially works well for huge changes in your organization or the introduction of savvy new products.
  • Headline the last date for a special offer. Most of us are always too busy and tend to put off taking action. “Save Money Now” and “Get Bonus If You Buy Now” offer to augment response.
  • FREE offers often draw the greatest response. There is a myth that wealthy or professional customers are turned off by free offers. This is not accurate at all. Just customize your free offer so as to match the style of your customers or industry.

Prospects are always hard-pressed for time. They are barraged with hundreds of ads, sales letters, postcards, and commercials every day. They tend to tune out any advertising message that looks like it will take quite long to figure out. Headlines help them decide. So focus on them.

A Strong First Paragraph

The next step is knowing how to begin your sales letter.
Do you tell the prospective client immediately what it is you’re intending to sell? Do you just stir him up a bit so he can comprehend why he would require your product or service?

The course of the initial paragraph of your sales letter depends on the theme you’ve chosen. That subject will dictate whether your lead paragraph will follow a specific creative approach or focus on your offer.

Here is a comprehensive set of the rules to follow in creating your first

  • Make it theatrical, interesting and directed to the exact target audience.
  • Keep your paragraph concise.
  • let your sentences be precise.
  • Keep your words short.
  • Use “you” to engage the prospect.
  • Make your message come from a single person, on a very individual basis,
  • with the aim of building a one-on-one readership throughout the piece.
  • In assessing any sales letter, one of the basic things you should do is examine the lead paragraph. Does it match the approach and taste of the six points listed above?

There is no rigid formula to a lead-in paragraph, but your letters will create
enhanced responses if you follow, rather than break the rules.

Include a P.S. In Your Sales Letter

People do like to know who has sent them the letter and tend to quickly scroll down to the end of the letter to see whose signature is at the bottom.

The next thing they see below the signature is a Postscript (or P.S.). Truly
enough, your P.S. can be the second (after the headline) or third (after the
opening sentence/paragraph) most read element of your sales letter or email.

Most copywriters use not just one postscript, but also several (P.P.S).

For marketers, it provides one final opportunity to influence prospects into
. The best way to use your final “addition” is to highlight or re-state a chief point of significance to the reader.

Employ these tactics. P.S. is one of the most-read elements of any sales
letter. It ranks second only to your headline and sub-heads in terms of
readership priority.

Keep it concise and precise. A succinct summary is sufficient to uphold the
reader’s interest. If you need more room, create a secondary P.S. Adding
supplementary P.S.’s is a mainly effective strategy with longer sales letters.

Include Guarantees

If you offer a product or service without a guarantee, you might just be on the verge of losing a great percentage of potential sales. Nowadays, scams are widespread. Since there is no official police or moderator on the Internet, such scams are most likely even greater as a consequence.

Because of these swindlers and the huge number of challenges presented on the Web, people are mistrustful and will increasingly seek out more protected means to advantage from offers. Guarantees are, therefore, influential tools for the opulence-seeking marketer and can do two very vital things that will help grow one’s profits: Increase sales and reduce returns.

When you offer a guarantee, you diminish the cynicism around the purchase of your product or service. Consumers are reasonably careful and all the more when making purchases via the Web. And guarantees give you almost immediate trustworthiness with possible customers.

Seven Tips for a Grand Guarantee

  • Make the guarantee easy and unqualified. Drop the excuses and fine print.
  • Be sure your total organization believes in the operating philosophy dictated by the use of guarantees.
  • Be familiar with your clients enough to realize whether the guarantee at all helps the client.
  • A guarantee should be a two-way road, so include some upside if you surpass performance potential: ask for “success” fees.
  • Indicate which clients can claim the guarantee and which cannot. Restrict the number to a minimum.
  • React quickly if a client requests that you make good on your guarantee.
  • Monitor your performance to save surprises.

Guarantees fall into five very different categories:

  • The Money-back guarantee: This guarantees that your customers won’t squander their time or money. It also defends customers if the product breaks or fails.
  • The Satisfaction guarantee: This guarantees that your customer will be happy and satisfied with your service or product.
  • Price protection guarantee: This can either offer a fixed price, ensuring the price and/or payment terms won’t change or increase (for example, life insurance) or ensure that they won’t find a lower price elsewhere.
  • On-time guarantee: This helps suppress the fears in time-crunched clientele. Businesses like printers, car repair shops, and cable companies can find such an offer tempting.
  • Absolutely No Questions Asked guarantee: This can be functional towards anything. Just try it out and see.

Fundamental Tips On How To Write An Effective Sales Letter.

Build Credibility.

Besides mentioning the benefits, you should also put in testimonials of people who have already used and benefited from your product or service. This builds credibility.

Make It Memorable For Your Reader.

Most unsolicited emails get tucked into the dustbin. Your mailer should have something unique for people to consider spending more time on it. For example, a car repair service might include the top 10 tips for car maintenance and so on.

Emphasize Aesthetics.

The letter should be user-friendly. It should have an attractive visual impact. The aesthetics should be well defined. Also, it should be easily navigable.

Include A Call To Action.

Include a postcard, prepaid envelope and/or an order form. If not appropriate, supply a toll-free telephone number, an email link, and/or your URL.

Always Include An Enticement.

The letter should include an incentive for acting promptly – a discount, special offer, gifts, and so on.

Resist Doing “Mail Merge.”

Technology has made life easier no doubt. But try to avoid writing mass mailers. Customize each letter according to the needs of the reader.

Forge Everlasting Connections.

Try and forge everlasting relations with your customers. For this, you have to “under-promise” and “over-deliver.”

Test Market.

Whatever technique you intend to apply, always test the market.

Hit The Right Chord.

Your sales letter should not be too formal and full of jargon. That might inhibit the reader.

One Final Tip:

Before sending out the mailers, make sure you have calculated all aspects. You would certainly not want to be flooded with offers without having the appropriate resources.


You don’t require being an award-winning copywriter to create proficient sales letters. In reality, writing great sales letters is more scientifically inclined than being an artist. Even the professionals use proven “templates” to generate sales letters that get the desired outcome.

Every individual has some form of buying resistance. The basic objective of your sales letter should be to triumph over your reader’s buying resistance while coaxing him to take action. These hurdles are noticeable in many stated and unstated customer comments such as:

  • “You don’t realize my real problem”
  • “How do I know you’re competent?”
  • “I do not believe you at all”
  • “I don’t need it at present”
  • “It won’t help me in any way”
  • “What happens if I don’t find it useful?”
  • “I can’t afford to buy it” and so on.

The sales letter must play on the reader’s emotions to the extent where they
would be inspired enough to take action. The letter should try to attack those “hot buttons” or emotional pressure points, which will persuade the reader to buy.
