Send Email to Customers Who Leave Reviews in WooCommerce

This custom code snippet enables you to automatically send emails to anyone who leaves a starred review in WooCommerce.

You can send emails based on any rating between 1 to 5 stars. In this example, the code sends an email you can customize, to anyone who leaves a 5 star review.

Copy and paste the following PHP code to the end of your child themes functions file or custom functionality/code snippet plugin.

add_action('comment_post', 'send_email_after_starred_review', 10, 2);

function send_email_after_starred_review($comment_id, $comment_approved) {

    if ($comment_approved !== 1) {

    $comment = get_comment($comment_id);
    $rating = intval(get_comment_meta($comment_id, 'rating', true));

    // Only proceed if the rating is 5 stars
    if ($rating === 5) {
        $comment_author_email = $comment->comment_author_email;
        $product_id = $comment->comment_post_ID;
        $product = wc_get_product($product_id);
        $product_name = $product->get_name();

        $subject = 'Thank you for your 5-star review!';
        $message = "Dear Customer,\n\nThank you for leaving a 5-star review on our product: $product_name. We appreciate your feedback and support.\n\nBest regards,\nYour Company Name";

        // Send the email
        wp_mail($comment_author_email, $subject, $message);

Code Modification

Swap out the 5 in the code to any other rating between 1 and 5.

Swap out the content between the “” double quotes to personalize your email message.

The code can be modified and extended to do anything you need.
