The convenience of emails overshadows traditional letter writing these days. Sending a letter is a great formality that could be useful for you in the future. You never know when you might need to write a letter, whether it’s for a pen pal or sentimentally thanking someone, writing a letter is a great skill to have.

Date. Write the date in the upper left-hand corner. You can include the address/recipient’s name and your name/the return address under the date or on the front of the envelope.
Greeting. In a formal letter, the standard salutation is “Dear” followed by the recipient’s title and a comma. Include their official title if they have one. (Dr, Miss, Ms., Mr., etc.)
Body. Introduce the letter’s purpose in your opening paragraph and then discuss your points in an organized manner. The final paragraph is a good place to thank the recipient for their time and summarize your points.
Closing. To end a letter you should always sign off. Polite ways to sign off include sincerely, respectfully, best regards, etc.
Signature. The final part of a letter is your signature. Include your full name and title if relevant
