Don't include quotes.
不要包含引言。

Avoid oversized corporate logos. Sometimes we have no choice about this, because our companies insist we include these things, but if they are too big, they draw the eye away from the message.
避免过大的公司标识。有时候我们别无选择，因为公司坚持让我们使用这些东西，但是如果标识太大了，它会分散注意力。

Include your title and contact info, but keep it short. In most business emails, you're doing the person a favor by sharing your vital information. But make it minimal. E.g., "Susan Adams, Senior Editor, Forbes 212-206-5571."
包含你的职位和联系信息，但是保持简洁。如：“Susan Adams，福布斯杂志高级编辑，212-206-5571。”

Do include some kind of sign-off.
务必包含结尾。
