Enable customization of Smart Coupon email headers and templates in WooCommerce >> Settings >> Emails
If the Smart Coupon plugin is activated, can you please add function for user control over customizing email headers and content templates in WooCommerce >> Settings >> Emails?
The email header and template settings have to be manually edited in the WooCommerce template file 'emails/email-header.php', and in the Smart Coupon template file 'woocommerce-smart-coupons.php'. They then have to be copied into folders on the child theme. Of all other emails that can go out from the WooCommerce system to customers, this is the only plugin feature I've found so far that is not controlled in the general Settings >> Emails feature.
yes it's sad that even after charging a bomb, woo fails us!
