How to write a letter to sell a product

Follow these four simple steps to successfully write a letter to sell a product:

1. Write an attractive headline

When writing the headline of your sales letter, it's important to capture the reader's attention as quickly as possible and entice them to continue reading. Try focusing on the curiosity of your target audience by promising a specific solution to their needs. Consider brainstorming several headline ideas before choosing the best one for your letter.

2. Explain your offer

After capturing a reader's attention and promising a solution to their needs, try to convince them that your product or service is the best option for their situation and offers more benefits than the competition. When writing the body of your letter, try asking yourself questions a prospective customer would ask themselves when reading. This technique may help you to better understand the type of benefits that would convince a reader to choose your product or service over the competition.

Consider explaining the benefits of your product or service in detail. If the paragraphs of your letter become too long, try separating them with bullet points and lists to make them more readable.

3. Provide proof of value

Often, customers want to feel certain they're making a purchase that adds value to their lives. Consider providing proof of customer satisfaction in the body of your letter, such as testimonials and positive reviews, to assure customers of the value of your product or service. This gives a reader confidence in their decision to purchase your product or service and builds trust between your brand and your target audience.

If you're unable to provide positive reviews or testimonials, consider offering a free trial or money-back guarantee to prove your product or service is a low-risk investment.

4. End with a P.S.

Adding a postscript (P.S.) to your letter is a great way to create a sense of urgency. Consider adding a final note to the end of your letter that offers something special to a customer if they make a purchase within a certain amount of time, such as a discount or free shipping. Urging your customers to act quickly decreases the chances of them continuing to browse and purchasing from another brand or business and could help you secure a sale.

Tips for writing a letter to sell a product

Below are some useful tips to help you write an effective letter to sell a product:

Be specific

When writing a letter to sell your product, consider being as specific as possible about your product or service's benefits. Detailed information about features and benefits helps customers visualize the ways in which your product could solve their problems and how it's better than similar products on the market.

List as many benefits as possible

It's important to outline as many benefits as possible without overwhelming your reader with too much information. Try to include the impressive benefits your product or service offers in short, concise sentences. Being efficient when describing the benefits of your product ensures that important information is available to a reader without losing their attention.

Be personal by referring to the reader by name

Often, customers want to feel they're purchasing products from a brand or business that understands their needs and genuinely hopes to provide solutions to their problems. Whenever possible, consider addressing your customers by name in a letter to sell a product. This builds trust and assures your customers that you care about them and the ways in which your product or service could add value to their lives.

Include a short business bio

Another technique to help your brand or business connect with your target audience is including a short business bio in your letter. Consider including how and why you began selling your product or service, your business philosophy or any other details about your brand, product or service your customers may be interested to know about. When customers feel you are genuine and believe in the value of your product or service, they may be more likely to complete a purchase and recommend you to friends and family.
