Undo youmail message

You're referring to the "Undo Send" feature in YouMail!

If you've sent a message and want to undo it, you can try the following:

1. Log in to your YouMail account on the web or mobile app.
2. Go to the "Messages" or "Voicemails" tab, depending on the type of message you sent.
3. Find the message you want to undo and click or tap on it.
4. Look for the "Undo Send" button, which is usually represented by a clock icon or a "Revoke" button.
5. Click or tap on the "Undo Send" button to cancel the message.

Note that the "Undo Send" feature is only available for a short period of time after sending the message, usually around 5-10 seconds. If you don't see the "Undo Send" button, it may be too late to cancel the message.

Also, keep in mind that the "Undo Send" feature only works for messages sent through YouMail, and not for messages sent through other messaging apps or services.
