Inquiry go to 2nd email

running property with a 2nd owner. I have theming set up, triggers sending with correct info.

How do i get an inquiry from the "booking" page to send to the 2nd email and not the primary account email holder? Or at least send to both.

Unfortunately, at present, you cannot, at least not through OwnerRez.  But, most email inboxes have a capability for filtering and forwarding emails that match certain parameters, so, you could likely configure that in your primary account email to forward those messages onward to some other address.
