Pull back email

You want me to pull back an email, but I'm not sure what that means. Could you please provide more context or clarify what you mean by "pull back an email"?

Are you trying to:

1. Retrieve an email that you sent to someone and want to recall it?
2. Delete an email that you received and want to remove it from your inbox?
3. Undo a mistake in an email that you sent and want to correct it?
4. Something else entirely?

Please provide more information so I can better understand what you're trying to do and assist you accordingly.
