英文信件书写主要以能够让收信人获得信件内容为主要目的，因此，邮件或书信的语言应该尽量言简意赅，简明扼要的表达出来主要意图。
一、信件格式
英文信件书写主要以能够让收信人*获得信件内容为主要目的，因此，邮件或书信的语言应该尽量言简意赅，简明扼要的表达出来主要意图。英文书信表达主要分为以下几类：请求信，建议信，道歉信，抱怨信，感谢信，求职信及咨询信等。尽管不同类型的信件中具体的诉求内容不同，每种书信类型的结构构架极其相似。书信写作通常包括三个部分：称呼、正文、落款。
1、称呼
称呼是信件开头对收信人的称谓，根据与收信人的关系使用恰当的表达。
(1)如收信人为未见过面的陌生人、机构或团体时，称呼通常为Dear Sir 或Dear Madam;如能知道对方职务，也可以按照Dear Professor或Director等开头一表示礼貌。
(2)如若收信人为日常一般交往或工作上有来往的人，称呼可以用Dear Mr./Ms.+收信人的姓氏。
(3)如若收信人为熟悉的人，则可以用Dear后加名字开头。
2、正文
在格式方面，英文书信一般采用齐头式，即每段开头顶格，段与段之间空行。齐头式会使得信件层次分明，条理清晰。
在内容方面，信件正文一般分为四个主旨段。根据信件功能和目的的不同，每段具体内容会有变化，每一段大概写作方向为：主旨段一简单的提出书信的目的，例如主要目的是建议还是感谢等;主旨段二写这封信件的原因;主旨段三进一步提出希望达到的效果;主旨段四表达想要尽快收到答复或对方能够给出相对的回应。
3、落款
落款一般为yours faithfully或yours sincerely加署名。其中，在写给机构，教授等正式书信中，署名建议为全名。在写给朋友的书信中，署名可以与称呼中朋友名字相呼应，如只称呼朋友的名如George，落款署名则相应的是名如Thomas。
