保持亲切随和 Always be polite

In reality you wouldn't stop chatting to someone in the street mid-flow if they were boring you in a conversation; however, online you can. If an email conversation starts out well but then you realise this person isn't 'the one' then politely back away. Failing that, if they don't take the hint, then their emails conveniently getting 'lost in cyberspace' or ignoring all contact should also work.

现实生活中，即便对他人的谈话感到厌烦不已，你也不会断然终止对话。但在网上却可以。如果最初的邮件往来很好，后来却发现对方不是想要的那个"真命天子"，你大可礼貌地终止这种交流。如果对方没看懂这种暗示，你还可以假装没收到邮件或者直接忽略这种沟通方式。
