慰問信是公司間友好往來的信種之一。商業伙伴出了事故或是公司要人去世，都應該寫一封慰問信，以表示關心。這樣的友好往來也會給雙方的關系帶來好處。
慰問信一定要注意措詞和語氣。下面是寫慰問信需要注意的幾點：
1. Start with a statement of sympathy.
2. Follow with sentences about mutual experiences or relationship.
3. Close with some expressions of comfort and affection.
下面是一封悼念業務伙伴的慰問信，可供參考：
Dear President Anderson
We were distressed to read in the Times this morning that your Chairman, Mr. Yonga had passed away and I am writing at once to express our deep sympathy on behalf of my colleagues.
I had the privilege of knowing Mr. Yonga for many years and always regarded him as a personal friend. By his untimely passing our industry has lost one of the ablest leaders. We at the representative office in London recall his many kindnesses and the pleasure of doing business together with him. Mr. Yonga will be greatly missed by all of us who have known him and worked with him in building a better community between our two businesses.
Please accept our deepest sympathy and convey our best wishes to Lady Yonga and her family.
