有明确的目的
在开篇之前。Dear Sir/Madam （你完全不知道会看你这封邮件的人是谁的前提条件下）Dear xxx Committee/Organisation/Office (写给某某委员会或者办公室的）Dear Prof./Dr./Mr./Mrs./Ms./Miss. (对方的姓）（在你知道对方是谁，但是和对方不熟的情况下，一定要加前缀，以示礼貌）
开篇有很多种：最常见的是没有任何目的打招呼。如：Good morningGood afternoonHow are you?how was your weekend/holiday?Hope this email finds you well.I hope this finds you well.I hope you enjoyed this weekend/holiday.I hope you're having a wonderful day.这些是比较正式的开篇，就是不会出错的万能开篇。
如果你想以私人的口吻写开篇：Congratulations on [recent accomplishment]How did [recent project] turn out?I hope you enjoyed your [event or vacation]I loved Your recent [photo/article/social media post]I was just laughing the other day about [inside joke]I was just thinking about you and [shared memory]It was great to see you at [event]This [article/video/GIF] made me think of you[Mutual Contact] recommended I get in touch with youJust checking inHow is everything?Just checking to make sure that...I wanted to reach out to you because...I am looking forward to...这些句子一般是写给外国的朋友或者亲人的。
如果是回复对方邮件的开篇：It’s great to hear from youI’m eager to get your advice on…I’m reaching out about…It was great talking to youIt was great meeting youThank you for your helpThanks again for your helpThank you for your message/email/phone callThank you for the updateThanks for getting in touchThanks for the quick responseThanks for the additional info.这些都是比较正式的回复邮件的开篇。
还有一种开篇是走比较funny路线的：Happy “Not Monday”Hello from the other sideHere’s the good news: Only [number] more days until FridayHope you’re surviving another workweekI hope you’ve had your coffee alreadyIt’s me againI’ll keep this shortI’m sorry if this Message sabotaged “inbox zero” for youJust what you want: another email!我个人也挺喜欢的，但是从来没敢用过。。。
开篇之后，另起一段说明你这封邮件的目的就可以啦。
