Answer:
Return Address
Step-by-step explanation:
There are primarily 7 parts of a letter and these are the following:
1. Letterhead/Heading (business) or Return Address (an individual)
2. Date
3. Inside Address
4. Salutation/Greeting
5. Body
6. Complimentary Close
7. Signature
The "Return Address" refers to the address of the sender. This includes the name of the sender as well. This is very important especially if the letter requires a response from the recipient.
