Gmail UNDO Send is a function tested by the Google company for 6 years with the Gmail service, it allows the cancellation of sending an email to a person in order to avoid the transmission of wrong, humiliating information, etc.
Because the function proved to be a success, those from Google decided to offer it on a large scale to users, including those who use the Gmail service on iPhones, iPads or iPod Touches, they can very easily cancel an email sent to any persons.
For now, only the application inbox launched by Google has this function available in iOS, it being displayed in a way similar to the one visible in the video clip below, canceling the sending of an email being done in just a few seconds and without much effort.
Canceling the sending of an email using the UNDO Send function is available for a maximum of 10 seconds after pressing the button to send the email, so you must be very quick to cancel, otherwise the message will reach its recipient.
