1. You'll need to grab an account at http://joomlashack.intellicontact.com
2. Get a secret key and password for this application from Intellicontact
3. You'll need to add this code to func.php before:

# Send notifications to orders department and providers when product amount in stock is low

(about line 3216)

        # Subscribe the customer to a list at IntelliConnect. X-Cart support team (zaa@cdev.ru) #537293395 [[[
        require $xcart_dir."/include/intellicontact.php";

        $ic_key = "";
        $ic_secret = "";
        $ic_login = "";
        $ic_password = "";
        $ic_list_id = "";

        $contact_data = array(
            "prefix" => $userinfo['b_title'],
            "fname" => $userinfo['b_firstname'],
            "lname" => $userinfo['b_lastname'],
            "email" => $userinfo['email'],
            "address1" => $userinfo['b_address'],
            "address2" => (!empty($userinfo['b_address2']) ? $userinfo['b_address2'] : ''),
            "city" => $userinfo['b_city'],
            "state" => $userinfo['b_state'],
            "zip" => $userinfo['b_zipcode'],
            "phone" => $userinfo['phone']
        );

        $res = ic_handle_subscription($ic_key, $ic_secret, $ic_login, $ic_password, $contact_data, $ic_list_id);
        # ]]]
}

Enter in your account info, secret key etc as appropriate.
