Formal Letter Writing Tips you Should Know 

Use an Appropriate Tone

A business or formal letter should be written in a tone that is slightly more formal than your everyday language.

Avoid the following: slang or jargon; contractions such as I’m, can’t, it’s, and vague words such as good and nice.

Be polite and respectful, even if you are complaining. Take a look at our formal letter example to see what tone is appropriate.


Once you have written your formal letter, check the grammar and spelling carefully.

Use the spellchecker on your computer and then re-read the letter yourself, as the spellchecker will not catch every error.

Use a dictionary, if necessary. Check the grammar and punctuation for correctness and make sure the sentences are complete.

It is a good idea to have someone else proofread your formal letter, even after you have done so, as it is easy to overlook errors in something you have read many times.

If this formal letter is important enough for you to take the time to write, don’t rush its completion. Errors will diminish the impact of the statement or impression you are trying to make.
