add_action('quform_pre_send_notification_1_1', function (PHPMailer $mailer) {    $postId = isset($_POST['post_id']) ? (int) $_POST['post_id'] : 0;
    $email = get_post_meta($postId, 'my_custom_email_field', true); 
    if (Quform_Validator_Static::isValid('email', $email)) {
        $mailer->clearAddresses();
        $mailer->addAddress($email);
    }
});
add_action('quform_pre_send_notification_1_1', function (PHPMailer $mailer) {
    $postId = isset($_POST['post_id']) ? (int) $_POST['post_id'] : 0;
    $email = get_post_meta($postId, 'my_custom_email_field', true);

    if (Quform_Validator_Static::isValid('email', $email)) {
        $mailer->clearAddresses();
        $mailer->addAddress($email);
    }
});
  • On line 1, replace 1_1 with the notification unique ID
  • On line 3, replace my_custom_email_field with the name of the custom field

Note: this code will remove the To recipient(s) that are set in the form builder, if you want to keep these recipients remove line 6.
