英语书信作文署名格式【一】
近来英国商业书信信内地址并未依次缩进，似乎与美国式相同。此外，在美国还流行一种普通收信人地址的写法，就是在书信的Inside Address中，把门牌号和街名都省略掉。在英文书信中要使用敬语，最普遍的敬语是Mr, Mrs和Miss（用于未婚女性）。英国人常在男性的姓名之后用Esq. （Esquire的缩写），不过在商业上也在慢慢地改用Mr. Mmes.（Madam的复数形式），用于二个女士以上。Messrs（Mr的复数形式）用于二个以上的男人，或用于二个以上的男人组成的公司或团体。在英国式英文信里，Mr, Mrs, Messrs，均不加缩写句点，相反地趋向于进步自由的美语反而加缩写句点如Mr., Mrs., Messrs.。在称呼方面，商业上最普遍的有Gentlemen（美国式）与Dear Sirs（英国式）二种，相当于我国的“敬启者”或“谨启者”。
典型的美国式书写法。
给公司单位写信时美语用Gentlemen（复数形式），英语用Dear Sirs。如果对方公司只一人时，必须使用Sir/Dear Sir。称呼后一般要使用标点符号，英国式采用逗号（comma），美国式用分号（colon）。书信结尾客套语（complimentary close）有多种，相当于我国书信在结尾时使用的“敬礼”、“致敬”、“顺安”等句。最为典型的美国式写法是Sincerely和Best regards，典型的英国式表达有Yours sincerely（熟人或知道对方姓名），Best wishes, kind regards 和yours faithfully（不知姓名）。此外，英国式的客套语还有特别礼貌的格式，但除了特殊情况外，现在不再使用。

一封信写完了，突然又想起遗漏的事情，这时用p.s.表示，再写上遗漏的话即可，要长话短说。通常在信末签名下面几行的左方，应于正文齐头。
注意：在正式的信函中，应避免使用附言。
