Undo a sent mail on Gmail - We all need this
And now there is no undo or rewind button!
But, now we have remedy for this due to a little known feature that was added to Gmail Labs this month.
(Note that: Labs is a testing space and anything in there is subject to change.)
To enable 'Undo Send':
1. Log in to Gmail and go to Google Labs. It's in the left-top-corner >>go to More>> go to Even More
2. In the column on the right, click "Labs."
3. Click "Gmail Labs" in the column on the right.
4. Scroll down all the way to the bottom until you see "Undo Send."
Click "enable" and "Save changes"
5. Now, go back to the main Gmail page and click "Settings" in the top right. You should also see your green Labs icon there now. This will let you go straight to Labs from now on.
6. Scroll down to "Undo Send" -- it should be right above "My Picture." Your default should be set to 10 seconds. But you can use the drop-down bar to stretch that to 30 seconds.
7. Scroll down and hit "Save Changes."
8. To undo an email, just look for the box at the top of the screen that will have the words "Your message has been sent." After that, you should see the "Undo" option. Click that and you'll be sent back to the e-mail's draft form, where you'll have 30 seconds to edit or delete it before it goes out.

I know that 30 seconds is too less. But then, technology gives us very less chances to correct our mistakes. 😁
