The Complimentary Close and Signature Line The left edge of the close and signature line in a friendly letter begin in the center, at the same column as the heading.
The complimentary close begins with a capital letter and ends with a comma.
Skip from one to three spaces (two on a typewriter), and type in the signature line, the printed name of the person signing the letter. If the writer and reader are very friendly, or if the letter is handwritten in the same script as the signature, the signature line or the last name in the signature line may be omitted.
Sign the name in the space between the close and the signature line, starting at the left edge of the signature line.
Unless there is great familiarity between the correspondents, the signature should be in blue or black ink.
Truly yours, (Signature goes here)
