Remove shipping info for free shipping method on WooCommerce email notifications

Question

When the customer order is placed, I would like if free shipping has been used, to remove shipping info from the order confirmation mail to the customer.

Is it possible to achieve this?

Answer 1

This is possible with this custom hooked function (but from all email notifications):

add_filter( 'woocommerce_get_order_item_totals', function( $total_rows, $order, $tax_display ){

    // Only for "Free Shipping" method
    if( ! $order->has_shipping_method('free_shipping') || is_account_page() || is_wc_endpoint_url( 'order-received' ) )
        return $total_rows; 

    unset($total_rows['shipping']);

    return $total_rows;
}, 11, 3 );

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested and works.
