Gmail: Google Finally Launches The Long Awaited 'Undo Send' Feature

After what seems to have been the longest beta period ever, Google has finally graduated Gmail’s “Undo Send” option from labs into a permanent spot.

When you enable Undo Send, you’re able to “unsend” an email up to ten seconds after you hit the send button — Gmail just delays sending briefly so you have a moment in case you change your mind.

To enable Undo Send:

• Click the gear in the top right .
• Select Settings.
• Scroll down to “Undo Send” and click Enable.
• Set the cancellation period (the amount of time you have to decide if you want to unsend an email).
• Click Save Changes at the bottom of the page.
