Hi,
Customize WooCommerce Order Emails
1) Override a custom Email WooCommerce Template
– First you make sure that the following directory exists in the WordPress installation: wp-content/themes/your-theme/woocommerce/emails.
– Next, copy the file found at wp-content/plugins/woocommerce/templates/emails/… into the store’s theme at: your-theme/woocommerce/emails/.
– Finally, edit your-theme/woocommerce/emails/…
2) Conditional Customization with Actions/Filters
– The most effective approach to customizing emails is to work with WooCommerce custom code. This obviously requires a high-level of expertise in PHP.
WC_Order::get_cancel_order_url() – Generates a URL so that a customer can cancel their (unpaid – pending) order.
