The Inbox Zero extension for Gmail is a fantastic way to celebrate when you clear your inbox. The extension replaces Gmail's default empty inbox message with a random GIF from Giphy, and you'll get an email notification every time it happens. If you're running it on your Gmail app, you'll see your email notifications on the new tab.

The Inbox Zero extension also has the option of showing you a GIF with a message that appears on your web page. If you want to include a message that appears in the GIF with the email notification, simply include the message and click the download button.

The Inbox Zero extension for Gmail works with both the regular and priority inboxes for Gmail.
