How does a Mac system create a smart mailbox?

1, on the Mac open mail application, please click on the top left corner of the window "Mailbox" option, as shown in the picture

2, in the lower left corner of the mailbox list has a + button, please click Continue, as shown in the picture

3, then in the menu appears, please click the "New Smart Mailbox" option, as shown in the picture

4, then will pop up a small window to set up a smart mailbox. For example, here I'm going to create a smart mailbox called unread, and then click on this "unread" mailbox to see all the unread messages.

5, then in the mailbox conditions Drop-down list, I choose the "message unread" option, as shown in the picture

6, can set up a number of conditions here, according to their own needs to set. I just set an unread condition here and click the "OK" button to save it.

7, then in the mailbox list under the "Smart Mailbox", you can see that we have just created the "unread" mailbox. It is not convenient to click on it to see all the unread messages in the current message.

8, of course, in order to make it easy to quickly click on the smart mailbox, you can also drag it directly to the top of the mail window.
