An undo button for email has been desired by email users ever since the inception of the online mode of communication. Gmail had introduced this option six years back but now it has officially been added as a regular part of Gmail.
Users can enable this feature by accessing settings and selecting the “Undo Send” section. Gmail gives an option having various time periods of 5, 10, 20 and 30 seconds in which you can use the Undo Send option.
In case if a user sends out an email that was not supposed to be sent, he or she will have precisely that many seconds to change their decision and hit the undo button at the top of the page.
