聊天！邮件closing结尾

不知道从什么开始，我也可以跟人一聊聊三四个小时，当然主要是对方说，而我在听今天又是一个三小时，快乐着！

The most formal way is to use Sincerely.

Sincerely，

Jack

Kind/Warm/Best regards,

Best wishes,

REGARDS,

All the best,

Notice that we always have a comma after the closing.

We can just put our name at the end.  Sometimes with a dash连接号 before the name.

Write your name on the next line after the closing.  You can also include your position the company you work for and your telephone number.
