Product SKU in Emails

Hey,
By default, SKU shows for admin emails and not for customer emails. That is how Woocommerce is set up. to change that you have to edit woocommerce and how they output order items.

You can use this filter: ‘woocommerce_email_order_items_args’

see here: https://github.com/woocommerce/woocommerce/blob/master/includes/wc-template-functions.php#L3129

I hope that helps!
