This is an interesting extension in Chrome which allows us to check our Gmail account without even launching Gmail! Once it is installed in Chrome, you can get notifications, read, hear or even delete mails without opening Gmail. You can also handle multiple Gmail accounts. If you get an email while you're busy watching a movie or cooking dinner, this extension can optionally read it out aloud; for example, "Amar says, dinner at my place.”
There is an option to have a popup mail preview window to read, archive, mark as read or delete emails without leaving the current tab (or option to go directly to your Gmail tab). Customisations include the ability to configure which inbox labels get shown, set up a ‘Do Not Disturb’ window, alter the look and appearance of the add-on window and more.
A very useful extension for Gmail, especially if you use multiple accounts!
