Remember how letter writing can be very challenging while being taught in school? There are times we desire to write a formal letter but end up writing an informal letter. Knowing how to write a formal letter is very essential for everyone especially if you work in a corporate firm.
However, In recent times social media has transformed the way we communicate through letters. Now, these letters have turned into emails. In this article, we will shed light on how to write a formal letter, its types, and more.
What is a formal letter?
A formal letter can also be known as a professional or official letter, which is direct and uses formal language. Most importantly, such letters are detailed with few words and a few paragraphs that convey the central message to its reader in seconds. These letters are written to authorities, dignitaries, colleagues, and senior officials.

How to write a formal letter: Simple steps
Some simple steps to follow when writing a formal letter are:
Writing the contact information
All formal letters begin with two addresses all in block format, located at the top right corner and top left corner respectively, which consist of the contact information and date.
However, if you are writing an official letter with letterhead information, you don’t need to rewrite the contact information.
Firstly, the sender writes his/her address, city/state, country, and date, all aligned and in a block format at the top right corner of the letter.
In addition, It is followed by recipient contact, name of the company, city/state, and country; all aligned and in block format at the top left of your letter, immediately below the first address.
Salutation
Formal letters always have a written content greeting located immediately after the contact information. Most of these greetings begin with ‘Dear’ accompanied by the recipient status as it shows acknowledging the recipient with due respect before the main information is passed.
Writing a salutation can be very easy and at the same time technical. If you do not know the name of whoever the receiver is, it can be addressed as Dear Sir/Ma. Also, the receiver can be addressed based on his/her current position in the job title posted such as Dear HR. You must try to avoid writing ‘Dear Sir or Madam’.
Writing the subject/topic
When a strong and direct subject is composed in a formal letter, it conveys the meaning of the entire letter just in one line to the receiver. The subject can be long or short with not more than seven (7) words, it could be written in capital or small letter case.
Subjects in formal letters are located immediately below the salutation, with not more than seven words. When it’s written in small letters, you are meant to underline it but when it is written in capital letters, you don’t underline it.
