Many of us have sent an email inadvertently to the wrong person realizing only after clicking the send button. Or after a moment of thought regretted sending an email and realized too late it was not the best idea to send it but it was already in the recipient’s inbox.
Gmail is rolling out an undo send button to allow people a moment of pause before you can’t take it back. On Gmail’s webmail only, you will have the option of 5 to 30 seconds to retract a sent email. This is not without drawbacks; the undo send button will delay all of your messages from being received by the intended recipient which is not always convenient in this fast paced world.
