How to Undo Sent emails in Gmail

It happens to all of us, when you finish writing an email and without realizing that you have made a typo error or forgot to add some recipients, you hit the send button. Later you realize you did the mistake and can’t do anything. You have to send email again to missing recipients and for typo error.

Now for Gmail users having option known as the “Undo Send” feature. It lets you un-send an email for a short period after sending.

After a beta period for last six years, Google has finally introduced Gmail’s “Undo Send” option for its account holder. Google has first introduced the “Undo Send” feature to Gmail in March 2009 but the feature was available in experimental labs.

The Gmail Labs feature, started on June 5, 2008, allows users to test new or experimental features of Gmail.

But there is a catch, you can only ‘undo send’ an email from 5 to 30 seconds of hitting the send button, depends upon your settings. It allows you to do setting from 5 to 30 seconds.

It delays sending the email based on your settings, so that if you change your mind, you can do option ‘Undo’.
