感谢信是为了感谢其它企业或者个人对我方的业务支持、协助而写的礼仪信函。与致辞、贺信等等一样，感谢信函的公关功能要比商务内容大得多。西方的通常做法，逢年过节，或者客户向你或者公司提了建议、善意的批评，或者时机恰当，都会寄出书面的致谢信，向对方的长期合作、支持、甚至正常的订货、付款等业务活动表示感谢。也正是因此，感谢信函经常与贺信揉到一起写。如今打电话的确方便，但是如果事件较大、场合正式，打过电话依然需要撰写书面的感谢辞，寄送方式当然可以利用电子邮件。感谢信的写作格式与一般信函大同小异。

感谢信的特点主要体现在内容的组织结构上：

1、说明感谢谁，因而对方的姓名、称呼、职务必须具体、明确

2、概括具体事情，务必让对方明白说的是哪件事

一定要说明对方的帮助产生了什么样的效果和客观影响

3、把表示感激的话说出来，不要含蓄

4、热情赞扬对方的协助精神，适当应用一些套语

5、不必沿用汉语同类文本的套路，即不要表示“向你学习”、“以后厚报”之类;文字要精炼，表达应清晰、准确、客观，篇幅应当短小。感谢、赞扬时，尽量要恰当得体，体现出真诚的感谢之情。感谢信函的主要信息是表达感谢和感激的心情，不要牵扯其它内容。
