There are times when we want to recall an email that already sent out accidentally. With Gmail account we have up to seconds to recall the email, or in Gmail they called it undo email.
Unfortunately, this is not a default feature, we need to activate it first before we can use it. Follow below steps to activate undo email (recall) in Gmail account.
1. Click the gear button on the top right side in Gmail, scroll down and click Settings
2. On the General tab, scroll down until you find Enable Undo Send, put check mark before it, and choose how long you want Gmail to allow you cancel email, you can choose up to 30 seconds.
3. After enable undo send activated, don’t forget to save it by scroll down the page until you see Save Changes button.
4. Send email to test whether email recall has been successful. After you send email you will see Undo link to recall email. This link will recall email sent from Gmail.
I love this feature and I personally active this on my Gmail account.
