Deleting forms forwarding to no longer existing email account

Hi here, I have an account with you ( rental application ) and when prospective clients submit the form it automatically forwards the completed form to 2 email account patiowest@telus.net and lainej@telus.net  The lainej account is no longer and I would like to delete it but can't seem to figure out how. 

You can remove the email recipients in the notification email by following this guide: https://www.jotform.com/help/314-How-to-Properly-Add-Change-and-Test-a-New-Email-Recipient-Address

Please give it a try and if you need further help, let us know. Thank you.
