If you decide you don't want to send an email, you have a short time after to cancel it. Immediately after you send a message, you can retract it:

  1. In the bottom left, you'll see "Message sent" and the option to "Undo" or "View message".
  2. Click Undo.


The timeframe to recall a message is dependent on the mailbox settings:

  1. In the top right, click Settings See all settings
  2. Next to "Undo Send," select a Send cancellation period of 5, 10, 20, or 30 seconds.
