checkout page – email notices and add an edit link (button)

Hi,

I am testing coupons and I bailed before completing transaction. I am still getting the notices, “You submitted a listing at xxx. This email is just for your information. Your listing will be reviewed shortly.”, but I did not complete the order. This may confuse people who decided not to continue. Is there a way to only have notices go out if the process is completed?

Also, is there a way to have a “go back and edit”, “go back…” link/button on the checkout page? A shortcode perhaps?

Thanks!!!
