helpful_feedback_email_subject

If you want to change the subject of your outgoing emails for your feedback form, you can do that with this filter as well. This filter overwrites the title.

/**
 * Replace default email subject for feedback emails.
 *
 * @param string $subject
 * @return string
 */
add_filter('helpful_feedback_email_subject', function (string $subject) {
    return 'My subject';
});
