If you’ve ever sent the wrong email to one of your contacts, you’d know that, depending on the content of the email, it can make for an extremely embarrassing and stressful situation. That’s why today, Google has brought the convenient “Undo Send” feature to Gmail on the web for those situations. The feature has actually been available for some time as part of the Gmail “Labs”, but now it’s available for all to use.
To enable it, go to mail.google.com, click on the settings cog on the top right of your screen, then choose Settings. Scroll down in the General tab until you see the “Undo Send” option, and check the box to enable the feature. Oddly enough, Google has given users an option to choose between 5, 10, 20 or 30 seconds for the cancellation period. I don’t really know why one would choose to only undo emails within the first 5 seconds when there’s a longer 30-second option available, but it’s there if you want to live on the edge.
The “Undo Send” functionality isn’t currently available in the Gmail mobile application, though perhaps it will make its way to the app sometime soon now that the feature is baked in to the web experience. Right now, the only way you can use “Undo Send” on mobile is through the Inbox by Gmail application.
