Have you deleted an email in an effort to keep your Messages organized, only to find that you really needed it? Don’t worry, we can help you get it back. At the bottom of the Messages tab you’ll see a Trash icon, where we send all of your deleted emails.
Click on this icon to see the emails you’ve deleted. Then find the email or emails you need to use and click the box next to it. Click the Restore button in the bottom right corner and your email will be returned to the Messages tab.
