That moment when you press send and immediately realize you made a terrible mistake. But it's too late. We all need to travel back a few seconds every once in a while, so with Inbox you can take back an email right after sending. Undo Send in Inbox launched a few weeks ago, and now it’s available on Android, iOS and the web. So enjoy those second chances!
Take a look at the video below to see the feature in action. You can download Inbox for iOS from here. Enable it on gmail.com by clicking the Settings cog button at the top right of the screen, choosing Settings from the dropdown menu, selecting the General tab, then checking the Undo Send box.
