How do I undo a sent email?
Please note this feature is available only on cloze.com and is coming soon to mobile.
If you decide you don't want to send an email, you have a short time to cancel it. You have five seconds to change your mind after you send an email.
Tap on the “Undo” button to stop the email from sending.
You can then continue editing your email and send it again as needed (or tap on the close button to save it as a draft or delete the message).
