Here is the way to the “unread” mails in your Gmail:

Make sure you are in your Gmail, type “is: unread” at the search field then click Search mail button (see the picture below):

And here is the result:

Tips: If you do this search repeatedly or generally appreciate brevity, you can use “l:unread” or even “l:^u” instead of “is:unread” (or “label:unread“).

And, you can combine the quest for unread messages with others:

• “l:^u from:Techtiplib” finds all unread messages from “Techtiplib“,
• “l:^u l:^t” finds all unread starred mail, and
• “l:^u l:^k subject:Giveaway” finds all unread messages with “Giveaway” in the subject that are in the Trash.

Hope this guide helpful for you!
