How to write a formal letter: step-by-step structure and examples

Official correspondence is an important part of business communication: its quality determines how quickly you will be understood and a decision will be made. Let's look at how to write an official letter so that the recipient sees the point and wants to respond immediately.

What is a formal letter and why to write one

A formal letter is an electronic or paper form document through which an organization or individual deals with business matters.
Examples of situations:

• the student asks the department chair to confirm the internship;
• the accountant verifies the details with the partner;
• The purchasing department sends the request to the vendor;
• the entrepreneur applies to the state agency for a license.

In all cases, the goal is the same - to convey information in such a way that the addressee understands what you are waiting for without unnecessary clarification.

Structure of a business letter

The following is the classic structure of a business letter:

1. Hat: company logo or your contacts, date, number (if needed), subject.
2. Greetings: "Good afternoon, Ivan!" or "Dear Mr. Petrov!". The wording depends on the format and the relationship.
3. First paragraph: the essence of the question. The recipient should immediately understand what the question is about.
4. Main part: arguments, details, documents, references.
5. Conclusion: a clear action for the recipient ("Please send the contract by July 5").
6. The final phrase: "Thank you for your attention", "I'll be happy to answer questions".
7. Caption: name, title, contacts.
8. Attachments: list of files, if any.

Rules of business correspondence

Business correspondence rules form a uniform standard within the company and save time.

How to write a business letter

The formatting of a business letter suggests the professionalism of the author.

• Format: in corporate correspondence, the electronic form (e-mail or corporate messenger) is most often used.
