We were able to modify the reply-to email for the 'new order' email that WooCommerce generates to the admin email of the site using the filter from this answer:
Custom "reply to" email header in Woocommerce New Order email notification
What we're hoping to do, however, is set the reply-to email to the recipient address that we've listed for the 'new order' email in WooCommerce > Settings > Emails.
We're also open to hardcoding the email we need the reply-to to go to into the above filter.
Would anyone be able to offer guidance as to how to do this? I'm a bit stuck. I don't understand what can be put into get_option( )
well enough to know how this can be successfully modified.
