Using one email address for everything that you do. Although you might think this is a good idea, this will make it harder for you in the long run. It's a lot easier to have separate emails for business, personal, even shopping needs. If you only have a few minutes and need to take care of something regarding business, you don't want to have to scan through a lot of personal emails trying to find the one that you're looking for. By keeping it separate it just helps you stay more organized.

　　用一个邮件地址做任何事情。虽然也许你认为这是一个好主意，长久会让你难办。将邮件分为个人、公司甚至购物三类就容易地多。如果你有几分钟的话，需要处理公事，那么就不会在个人邮件堆里找一封工作电子邮件。分开让你更有组织性。

　　Sending the email too fast. We know that everyone is busy and that you don't have a lot of time, but if your email is full of mistakes, it will make you look unprofessional to someone that you want to do business with. So just take a couple seconds to skim over everything you've written to see if that's what you want to say.

　　发邮件太快。我们知道每个人都很忙，没有时间，但是如果邮件中充满错误，这会让你在和你做生意的人眼里看来不专业，所以花片刻扫一眼写过的内容是否是你要表达的。

　　Also, when you rush, people have been known to forget the attachment. It may sound silly but there have been a number of times that people have sent me things that said "it's all explained in the attachment" when there was no attachment. This leaves me clueless and them looking very unprofessional. So just think about what you're doing and take the time to get it done right the first time.

　　而且在匆忙之中，你经常出现忘记附件的情况。听上去愚蠢，但有很多时候人们的邮件中称："附件中有详细解释"，可没附件。这会让我不知所云，而让他们看起来很不专业。所以认真考虑自己在做什么，花时间第一次就把事情办好。
