If a message is directly to someone — or more than one person — then you should put their address in the main address field.

如果消息是直接发送给某人——或者不止一个人，那么你应该将他们的地址放在主地址区域中。

For example, if you were emailing someone in your team about a project your manager was overseeing, you would put your team member in the primary 'To' address field, and your manager in the 'Cc' address field.

例如，如果你给团队中的某个人发邮件，内容是关于经理正在监督的一个项目，你应该将你的团队成员放在“ To ”地址区域中，经理放在“ Cc ”地址区域中。
