Which of the following is the best opening sentence for a business letter that you want to sound fairly informal?
A. I am in receipt of your order of February 10.
B. This letter is to make you cognizant of our receipt of your order.
C. Your order of February 10 arrived in our office today.
D. Please be advised that I've just received your order.
The point is -- which one do YOU THINK is appropriate for an informal tone?
Let us know what YOU THINK, and we'll be happy to comment.
