电子邮件不只是填写邮箱地址、主题和草草写几句那么简单。与其它书面沟通相似，发送一封电子邮件也需谨记恰当的格式，尤其是商务电子邮件。

1.首先要确定你的收件人邮箱地址是否正确。

If you don't, it will come back to you as undeliverable. Type in the email address in the "TO" box.

如果地址不正确，邮件会由于无法投递而被退回。把邮箱地址输入“收件人”框。

2.确定邮件的主题。

The topic is what should go in the "RE" box. Be specific, because the recipient may not know you; if she can't determine what the email is about, then she may hit the delete button--or worse, flag it as spam. Keep the email short and succinct. The first word of the title should be capitalized; all other words--unless proper nouns--should be in lower case.

主题是需要写在“添加主题”框里的。明确主题，因为收件人未必认识你，如果不确定邮件内容，也许会直接删除或标记为垃圾邮件。保持邮件内容的简短精炼。标题首字母需要大写，除此之外采用小写(专有名称除外)。

3.接着开始输入发给收件人的信息。

Even if the email is more casual, like an email to a friend or family member, take the time to prevent typographical errors, use proper form and use spell-check. To use spell-check, click on the icon marked "spelling" or "Spell check" and it will check the body of the email for errors and suggest corrections. After you have written the body of the message, read it out loud to yourself to make sure you've used proper English and haven't omitted any text.

即使是一封日常的电子邮件，比如发送给朋友或者家人的，也要花些时间避免输入错误，确保格式正确，并进行拼写检查。使用拼写检查的方法是点击“拼写”或“拼写检查”图标，系统就会检查邮件正文中是否有拼写错误，提出改正建议。在你写完邮件正文之后，自己再大声朗读一下，确保使用了恰当的语言，并且没有遗漏任何信息。

4,结束邮件时要采用诸如“最诚挚的”、“此致敬礼”之类的结语，然后加上你的名字。

If this is a business email, you should always type your email address and your telephone number below your name, as well as any other pertinent information such as your company and your title. Once you are satisfied with your email, click "Send."

如果是一封商务邮件的话，你还需要在名字下方加上你的电子邮箱地址和电话号码，以及其它重要信息，如你的工作单位以及职务头衔等等。当你对邮件感到满意了，就可以点击“发送”啦。
