Writing a sales letter can be a daunting task, especially if it is your first time trying to sell a product.

One of the biggest challenges people face when writing copy is a lack of proof.

This means that the lack of social proof and promotion makes it hard for people to trust the product they are being offered.

Inherently, people who come across a sales page or website are skeptical and assume that the seller is a scam artist.

So, how can you improve your sales copy to win over your audience and show them that your product is worth their investment?

Here are three tips to help you overcome the proof problem and write a persuasive sales letter.


Testimonials are an essential element of social proof that can help build trust with potential customers.

When people see that others have used and benefited from your product, they are more likely to trust your claims and make a purchase.

When you're starting out, it can be challenging to get testimonials, but there are ways to do it.

You can reach out to an online group or forum in your market and ask them to review your product for free.

This way, you can get feedback and testimonials that you can use in your sales copy.

Case Studies

A case study is a detailed story of how a customer used your product to achieve their desired outcome.

It's more in-depth than a testimonial and can be a powerful way to showcase the effectiveness of your product.

You can engineer case studies by finding people who are interested in your product and guiding them through the process to get results.

This way, you can get a result-based testimonial and a case study at the same time.


If you have a physical or software product, you need to show it in action to build trust with your potential customers.

A video demonstration of how your product works can be a great way to convince people that it's worth investing in.

Make sure the video is clear, concise, and highlights the most important features of your product.

In conclusion, writing a sales letter requires a lot of effort and skill, but these tips can help you overcome the proof problem and write a persuasive sales letter.

Use social proof, testimonials, case studies, and demonstrations to show potential customers that your product is worth their investment.

When you do this effectively, you'll see your sales conversions increase, and your business grow.
