Gmail has a brilliant feature of recalling a sent email or undo send email within certain specified time. This happens many times that we send the email to some other recipient or forget to attach the attachment with the message; this feature comes very useful in this case.
You must have noticed this feature besides the email sent notification as shown in the image above. If you have not come across this feature then you need to enable this feature by visiting the settings option. To activate this feature, you need to visit Settings -> Labs -> ‘Enable undo send‘ option.
Gmail has also increased the undo send time from earlier 20 seconds to now 30 seconds. To update the new undo send time you need to change the “Send cancellation period” again in the Settings option.
This is one feature that everyone should use as it reduces the unwanted message from being sent to the intended or unintended recipient.
