How to Find All Unread Messages in Gmail ?

To view all (and only) unread messages in your Gmail account:


Type "is:unread" (not including the quotation marks) in the Gmail search field.
Click Search Mail.
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").


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


"l:^u from:ashu" finds all unread messages from "ashu",


"l:^u l:^t" finds all unread starred mail, and


"l:^u l:^k subject:hi" finds all unread messages with "hi" in the subject that are in theTrash.


Enjoy! Now can Delete all unread messages....:-)
