Gmail is one of the most used & one of the best email service available online. If you use Gmail and receive large amount of emails daily it’s some time difficult to manage all the unread mails. In my case I had some 900 unread mail. Instead of selecting individual emails to make them as unread you can make a simple search in search box to get list of all the unread emails in one place.
- Go to Search Box
- Enter “label:(unread inbox)”
- Select all the emails displayed
- Click on Select all Conversations that match this search
- and select mark as read from More action drop down menu
You can use the same search query in Gmail for mobile also.
