I want you to know you have an exceptional employee, Jane Doe, in your support division. Her calm, patient manner was a great help to me when my frustration was at an all-time high. Her knowledge of the software and her remarkable problem-solving abilities are rare indeed. If the quality of a firm’s employees is an indication of future success, then Doe Corporation has a very bright future.

I am writing to thank you for the training seminar you arranged, and to especially thank you for sending Mr. Doe to be our primary instructor. He did his homework well, and was more aware of our needs than any of our previous instructors. We appreciate the time he took to study samples of our work in advance so his comments were immediately applicable. We would welcome his instruction again. Please convey our thanks to Mr. Doe.

I wish to commend your receptionist, Jane Doe, for the way she handled our problem yesterday. She was courteous and friendly as she made half a dozen telephone calls on my behalf, not giving up until she had traced the missing shipment. Such professionalism is rare nowadays. Ms. Doe is an asset to your organization and is part of the reason I look forward to doing business with you again in the future.
