How I Can Cancel The Sending Of Gmail

Do you  know that you can cancel a message sent by email in Gmail? This is a less known feature, but Google is better than it was before. When introduced, who gave five seconds of the window during which they could get to "cancel".

Now it's up to 30 seconds.

This feature is hidden for most users who do not know where it exists. Please note that the function is a part of Gmail Labs, however. This means that it is still in test mode and can not always go as planned.

Procedure:

1) Log into your Gmail account.

2) Gmail page, click the green button in a flask.
