How to Write a Congratulation Letter
- Write the congratulation letter as soon as possible 
 This is your chance to notice their special occasion. People love to receive a letter after a fortunate event takes place.
- State the specific occasion 
 At the beginning, express what motivated you to write your letter.
- Express praise and approval 
 Outline the reader's accomplishments and the good it has or will do.
- Keep your congratulation letter simple and concise 
 Usually under one page in length is enough—You want them to read it!
- Be positive 
 Don't include any negative comments or unhappy news.
- Don't suggest that the fortunate event should benefit the letter-writer 
 Even if your motive is to win a customer, don't let them know.
- Don't exaggerate your congratulatory words 
 Your letter may seem sarcastic or mocking.
- Edit your letter 
 Check for correct spelling, structure, grammar, and punctuation.
- Wait some time and proof-read your letter again before sending it 
 Most writers find errors or better way to express their thoughts.
