當獲悉某人晉升或是在事業上取得巨大成就時，應該打個電話或是寫封便簽祝賀。

　　這種友好往來對建立和鞏固友好的商業合作關系大有益處。

　　Here are some principles that congratulatory letters follow:

　　1. The purpose of writing the letter is to make your reader feel certain that he or she deserves the special message of recognition and praise.

　　2. The note should be brief, dealing with the primary topic only. These messages are most effective when they conduct no business.

　　3. The whole message should carry a tone of being positive and conversational.

　　4. Be sure to send the letter within a few days of the event. Any delay in delivery of the message would make your effort worse than no effort at all.

　　講過了祝賀信寫作應遵循的一些準則，下面我們通過一封信件來看看具體的寫作方法。

　　Dear Mr. Haskel

　　Congratulations on your recent promotion to head the Marketing Department of California Metals.

　　My fellow managers and I are delighted that your work in the marketing field has been recognized this way and we join in sending you our very best wishes for the future.

　　Through the five years of working together with you, many of us well aware of how much you’ve contributed to the association between our two corporations. We are all looking forward to your trip to China next month when we will celebrate your advancement in a more formal way.

　　Again, congratulations to you, Mr. Haskel - good luck and good wishes on your new position as Director of Marketing Department.

　　Cordially yours

　　(Signature)

　　Lin Daming

　　Marketing Director

　　在這封祝賀信中，寫信人一開頭就開門見山的祝賀收信者晉升，然后又詳細寫明自己對對方工作的欣賞、成就的肯定。在信件結尾的部分，寫信人用口語化的語氣再次祝賀對方的晉升，并以此結束信件。祝賀信寫起來很簡單，對吧?(來源：世貿人才網 )
