I have realized that many times I need to undo the action in Gmail when I realize that I did not want to send the email I just sent. Rather, it happened last week only, when I sent an email without attachment.
Thanks to Gmail labs, that introduced the Gmail Undo send feature day before that can allow you to undo the sent mail if you take action in 5 seconds. Though it’s short time, it’s good enough for accidental mistakes like “Oh no!” kinds.
It’s not the default option given, but you would need to enable it through your gmail labs settings. Just follow these steps, and you are all set for it.
1. Login to your gmail and go to settings
2. Click on labs and scroll down to search for “Gmail undo send” feature. Just search “undo” on that page.
3. Enable the option and save settings.








You are amazing! Now I can write an e-mail to talk trash about somebody without worrying that I accidentally send to that person.
