Writing a Formal Letter

Writing a letter can be difficult if you don’t know how to go about it. Note that you can craft an official letter if you know the recipient in an official capacity. Moreover, bear in mind that such letters are written to state departments or businesses but not to known individuals.


The following tips can help you craft an excellent formal letter.


  • Know when to compose a formal letter

A formal/business letter is addressed to a recipient who is known to you in an official capacity. A quite number of people craft business letters when applying for jobs or communicating officially to government departments.


It is advisable to type these letters, proofread, and edit them using software, such as word or Grammarly. If you are sending the letter to your current supervisor or workmate, you may use an email. In this case, you may treat it less formal, and you don’t have to include an address at the top of the page.

If you are writing a formal letter, write your name and address on the top-left side of the page. However, if you are crafting a business letter, you may use the company name and address. After that, skip two lines and write the current date. Note that you don’t have to include the date if you are writing an email.


  • Write the name and address of the recipient

After you have written the date, skip two lines, and indicate the contact information for the person you are sending to. Ensure that the details you provide include full name, address, company name, and address.

After writing the recipient’s contact, skip one line, and greet them with the name “Dear” followed by their full name/surname. If you don’t know the person’s name, you may use the job title, such as “Dear director.” In case you are not aware of the specific contact, use “Dear Sir/Madam.”


  • Compose the letter

Ensure you start your letter with a clear statement, and avoid using contractions (don’t use phrases, such as “didn’t” and instead write “did not.”). After you finish writing, proofread the document or let your friend assist you. If you are writing a letter for business, keep it formal and concise.


  • Use a complimentary close

Ensure that you finish your letter appropriately and establish an excellent connection with your recipient. For official letters, use phrases, such as “Yours sincerely” or “Your faithfully.”

If you are dealing with a formal typed letter, skip four spaces between the complimentary close and your typed name, print the letter, and append your signature in between the spaces. However, type your name after a complimentary end in case it is an email letter.


  • Fold the letter

If you are mailing the letter through post or courier services, fold it and put it in an envelope. Write the recipient’s address in the center of an envelope. You may also write your returnee address so that the letter is sent back if it is not delivered to the recipient.

Writing an Informal Letter

Informal letters are correspondences crafted in a personal way. They are typically addressed to friends, relatives, or to anyone whom you have a non-professional relationship with. You can write these letters to give advice, ask questions, request some details, or congratulate someone. Writing an informal letter requires you to be warm, friendly, and with an emotional tone.


Format of an Informal Letter

Note that there is no specific format when it comes to writing informal letters. However, people usually follow a general pattern to compose these pieces. The following is a description of the constituents of a friendly letter.

  • Address

Your address ought to be written on the left-hand side at the top of the page. Ensure that the details of your address are accurate and complete. Bear in mind that your contact information is still essential even if you are writing to your relatives. For your friends to reply, they need your address.


  • Date

Include the date below the contact details to enable the reader to have a reference on when the letter was crafted.


  • Greetings

The greeting used in an informal letter is casual. For instance, if you are addressing your friend, you may use their first name, such as “Dear Jane.” In case you are writing to an elderly or a respectable person, use phrases, such as “Dear Mr. John.”


  • Introductory paragraph

The opening of an informal letter should be informal and exciting. Ensure that you introduce your letter well to set an excellent tone for the entire correspondence. For instance, you may start by enquiring about how the recipient is fairing.


  • Body of the letter

The body’s content must convey a friendly tone; however, you have to frame the content based on whom you are sending the correspondence. For instance, you can write a personal letter if you are addressing a friend, but you must use a respectful language if you are writing to an elderly person.


  • Conclusion
