In a move that should prevent those accidental email sends to the wrong address, like sending your relatives or coworkers indecent proposals because they shared the same name as your ‘party of interest’, Google is bringing a feature that tries to prevent embarrassing moves – the Undo Send.
In order to enable this feature, you need to hit “Settings” i.e. the gear in upper right corner of the screen, and then again “Settings” in the drop down menu. Once you enter the “General” part of Gmail Settings, you should see “Undo Send” option, enabled by default. The cancellation period is enabled for 10 seconds, something which we would recommend you move to maximum allowed time – 30 seconds.
This should give you peace of mind for half a minute in case you sent the email to wrong addresses. The way how this works is quite simple – Google will not relay the message until the Undo Send feature times out. Naturally, if you leave 30 seconds to time out, there are no more ways to stop that email from going out and you’ll be SOL’ed.
Quite a good move, we would add.
