Yes it is still at the same location. Added the code:

// Change location of the checkbox
add_filter('anonymous_donation_checkbox_location', function() {
return 'woocommerce_after_order_notes';
});

Add checked if the following code was available in my plugin version

if (get_option("wcdp_enable_checkout_checkbox", "no") === "yes") {
    // Add checkbox to WooCommerce checkout
    $checkbox_location = apply_filters('anonymous_donation_checkbox_location', 'woocommerce_review_order_before_submit');
    add_action($checkbox_location, array($this, 'add_anonymous_donation_checkbox'));

    //Save the value of the WooCommerce checkout checkbox
    add_action('woocommerce_checkout_create_order', array($this, 'save_anonymous_donation_checkbox'));

    //Display the value of the WooCommerce checkout checkbox to the user
    add_action('woocommerce_order_details_after_customer_details', array($this, 'display_anonymous_donation_checkbox_in_order_details'));
}

That’s a pity, I think it can be useful for some WP developers to receive the content without any styling and scripts. But thanks a lot for your help, and “no” is also an answer. I going to have a look at the database solution.

Thanks a lot!

Thanks a lot! Get it. I will keep an eye on the official plugin update.

I tried this dev-version, but the problem is still there. I don’t have knowledge technically to analyse the email header properly to make mistakes visible.
