It's happened to everyone, you hit send on an email and realize you haven't attached a document or notice a spelling mistake.
If you use Gmail, the world is not lost. Gmail has a handy feature that lets you undo messages. By default, the undo command gives you five seconds to take back the email you sent, so you have to be pretty quick. Below we will see how to extend this time up to 30 seconds.
The easiest way to extend the time is to sign in to your Gmail account from a computer. Then follow the steps below
Click the Settings icon at the top right corner of the Gmail page and select the Show all settings option.
Find the Undo Send option and use the drop-down menu to change the time
Scroll down and click the Save Changes button.
Now, when you send an email, the undo option will be available for as long as you chose.
It's an incredibly useful feature that can give you some time to fix your mistakes.
