People respond positively when treated kindly. Employees work harder when they feel appreciated. With a sincere, well-written appreciation letter you can improve relations with words of admiration, gratitude, and recognition.
Write your letter quickly
Write your appreciation letter within a few days of whatever happened to inspire your gratitude.
Use stationery
Write your personal appreciation letter on a sheet of stationery.
Use customized letterhead
for business correspondence.
Address your appreciation letter to a specific person
If possible, not just to the company or to the organization in general.
Specifically state what you appreciate
Be sincere
most people can sense when you are not being honest.
Write clearly and concisely
This is no time to be longwinded or flowery.
Be brief
Avoid thanking the person beforehand
For example: "Thanking you in advance for your help in this matter." To do so is presumptuous and suggests you do not feel the need to write a follow-up letter.
Close with warm regards or best wishes for continued success
