写信时开头的称呼要顶格写，称呼后面要加冒号，信尾应写上写信人的姓名和日期。
书信是写给具体收信人的私人通信。除了保护有关的私人秘密外，一般对属于书面作品性质的信件也给予版权保护。在许多国家，实际上将所有书信当作文学作品，如法国、印度、英国、美国。有些版权法明确地把书信列举在受保护的作品之内(如巴西、尼日利亚、菲律宾等国）。
①开头称呼：顶格，有的还可以加上一定的限定、修饰词，如亲爱的等。
②问候语：如写“你好”、“近来身体是否安康”等,可以接正文。（不过很少。）
③正文：这是信的主体，可以分为若干段来书写。
④祝颂语。以最一般的“此致”、“敬礼”为例。“此致”可以有两种正确的位置来进行书写，一是紧接着主体正文之后，不另起段，不加标点；二是在正文之下另起一行空两格书写。“敬礼”写在“此致”的下一行，顶格书写。后应该加上一个惊叹号，以表示祝颂的诚意和强度。
