The principle of trust is to find a trusted medium, and through the trust of the customer in the medium, the customer will trust the supplier who comes to contact. The suggestion is:
It is best to ask a third party to recommend your company. Generally speaking, there are such professional companies in each industry that can recommend sellers to buyers, especially some professional media.
If you cannot get a recommendation from a third party, you can also list a recommender. This recommender can be an association, a partner of the customer, a bank, an industry magazine, etc.
If you want to make customers interested in your company’s information, you can use words such as Top, Leader, Largest, Unique, First, Award, and Member of. Use them boldly. It is recommended that at least one of these words should appear, and these words should be intentionally bolded or enlarged in the letter sent.
List 1~2 famous customers of the company, these customers may be the world’s top 500. Then the meaning is very clear: my products are used by the world’s top 500, the products must be good. If you want to optimize your supply, my company is definitely a good choice.
Finally, please specify the contact information of your company, including company name, address, phone number, fax number, website, etc., so that customers can learn more about you.
Finally, I suggest you buy a professional book on how to write English sales letters, which contains ready-made templates for your reference.
