劝说性书信的写作目的是向某个组织或个人提出劝说性建议的一种应用文体。先提出建议，随后给出充足的理由劝说对方接受你的建议，提出的理由要合情合理，用词要恰当，既要委婉礼貌，又要有说服力。
写作时注意以下几点：
1．形式要简洁，通常主要由称呼(Salutation)、正文(Body)、结束语(Closing)和签名(Signature)组成。
2．开门见山，直入主题。在书信正文的开头找准话题的切入点，自然而然地引出自己想要谈的主题。写信时要充分了解情况，有的放矢，以提高书信的针对性。
3．给出希望对方采取或者终止某种行为的理由。在陈述理由的过程中要换位思考，尽量为对方考虑。要用事实说话，以增强说服力。
4．语气要和缓，让对方考虑你的想法或者建议，以理服人是关键，不能把自己的想法强加于人。
5．给出合理建议，通过提建议让对方明确行动的方向，从而达到写信的最终目的。

参考范文：
Dear Wang Qiang，
I felt very worried when I heard that you were addicted to computer games. Although it's generally believed that computer games are interesting and can inspire our imagination, yet if you abuse them, they will be harmful to you in many ways. To begin with, they will waste too much valuable time which should be spent on your study or other beneficial things. In addition, playing games for a long time will do harm to your health, especially to your eyes. Worse still, some games are full of violence, which will be harmful to your mental health. Therefore, I strongly hope that you can break away from them. The earlier, the better. In order to live a meaningful life, you can read more good books, take more exercise to build yourself up or participate in some social activities to expand your horizons.
Looking forward to your good news.
Yours，
Li Ping
