I had around 125 unread mails in my Gmail inbox. And the fact that all these mails are widely distributed across 5 years of its existence made impossible to mark them as unread.
Here is the step by step procedure to mark all the unread mails as read on Gmail in no time:
- Login to your Gmail account
- Type is:unread in the search bar and hit on the Search button
- This will list out all the unread mails from your inbox
- Simply select them all and click on Mark button to choose Mark them as read
That is it! I wonder if you are aware of any other way which is as simpler and quicker as this one in your pursuit to delete all the unread mails from your Gmail account
