I don’t keep my Gmail inbox clean and I don’t open each and every mail I receive, but as the time passes, I finally end up with a cluttered inbox showing up some thousands of mails as unread.
I just want to clear this counter by marking the entire inbox as read. So how to I do that? well, here’s a really quick method to mark all the unread mails as read and reset the unread counter back to zero in Gmail
1. Type “in:all is:unread”, without quotes in Gmail Search box and hit enter
2. Now select all the mails using “Select All” option
3. Now click on “Select all conversations that match this search“
4. And finally, click “Mark as read” in the “More” drop down menu. Done.
This marks all your unread mails in your inbox as well as spam folder as read,
in:all is:unread – search result contains unread emails everywhere including inbox, spam, labels, categories, tabs and everything
in:inbox is unread – search result contains unread emails in inbox
in:spam is unread – search result contains unread emails in spam
category:social is unread – search result contains unread emails from social tab or category
category:promotions is unread – search result contains unread emails from promotions tab or category
label:hostgator is unread – search result contains unread emails from the label hostgator
There are lot more keywords to customize the search results and selectively mark emails as read or simply delete, just start typing in the Gmail search box and you will come up with new keywords and ideas.
