For everyone who has clicked send on an important email only to realise it contained a mistake, used the wrong name, or was sent without an attachment, Google is here to help.
To save you having to send the awkward follow-up apology email, you can now officially undo sent emails on Gmail.
The feature was recently added to Google for Work, but today has been added as a formal setting to Gmail on the web.
Undo Send lets you cancel a sent email immediately after sending it.
You can also choose how long you want Google to hold the email, to let you change your mind before it sends.
The options are 5, 10, 20 and 30 seconds.
To enable Undo Send, click the general settings tab on the right of Gmail, then click Settings.
The feature is turned off by default for those not currently using the Labs version.
However, people who are currently using the Labs version will have the setting turned on by default at launch.
