4. Failing to clean up the mess of earlier replies/forwards. Few readers will wade through strings of previous messages. State your position clearly, even if context follows below in the email string. 'Yes' helps less than 'Yes, you can have the extra funding to hire 5 temporary workers.'
误区四：喜欢用之前冗长的邮件往来内容来说事。很少有收件人愿意费力翻阅列在邮件正文后面的前期往来信息。应该把你的立场观点在正文中摆明，即便附后的内容也有所交待。单单回复“好的”太笼统，不如把话讲全，说：“好的，给你雇五个临时工的额外费用。”

5. Ignoring grammar and mechanics. PDAs have granted us certain sloppy flexibility, which means you'll impress readers even more when you write precisely.
误区五：忽视语法和结构。PDA的使用让人们对语法错误更为宽容，但这也意味着如果你的书写表达准确无误，人们会对你刮目相看。

6. Avoiding necessarily long emails. Longer messages sometimes work best; they can help avoid attachments' hassle and security fuss. Don't fear long emails but outline your structure.
误区六：不想写长邮件，即使言之有物。有时，邮件的内容越长，说得就越明白，这样就不用再添加附件，省得收件人打开附件时还要进行安全扫描。因此，不要害怕写长邮件，但要把内容的脉络结构理清楚。

7. Mashing everything together into bulky, imposing, inaccessible paragraphs. Length does not discourage reading; bulk does.
误区七：段落过长，内容太密集，让人读起来头昏脑涨。邮件的长度并不会让人望而生畏，但大段大段的排版却会如此。

8. Neglecting the human beings at the other end. Email travels between actual people, even though we don't see or hear each other directly.
误区八：忽视收件人的感受。要记住，虽然我们看不到对方，也听不到对方的声音，但电子邮件是一种真人之间的交流。
