When an appointment is made an email is sent to the site admin and the service provider. As the admin, I do not manage the appointments and certainly don't want unneeded email in my inbox. Unfortunately, there doesn't seem to be a way to remove the email from the admin without removing the email to the service provider.
Ironically, the unwanted email to the admin contains a convenient link to the pending appointment for confirmation but the link is not included in the email to the service provider who actually manages them. There seems to be no place to edit these notifications either.
