Typical business letters consist of six parts: title, address, body, closing, signature and reference.
Title: The title consists of two parts. The first introduces the sender. This is usually printed on the head of the letter. The second part is the “internal address” that indicates the date, the recipient’s title and address. Although the person he is writing to is someone you know very well, the title should definitely include these elements. Always write the sender and recipient’s information fully and properly.
Greetings: It is courtesy to start the correspondence with addressing. It can affect the relationship positively or negatively.
Body: The level of formalization in toning depends on the sender and receiver. If there is a personal relationship, a more comfortable greeting and correspondence can be written in the letter.
Closing: The closing section of business letters consists of two elements. The first (if this is the purpose of the letter) is a call to action or more assistance. The other is the words of praise before the signature. Most business letters end with good wishes.
Signature: The name of the author must be written; the handwritten signature must be just above it. The name of the signer should be immediately under the name if the title is not on the letterhead of the letter.
Reference: All business letters prepared by a person other than the sender may contain some references under the signature block
