You could use the UrlHelper.Action method:

public ActionResult Email()
{
    // Notice the last parameter which contains the protocol:
    // this one is important if you want the helper to generate
    // an absolute url. If you don't specify this parameter the
    // generated url will be relative
    string url = Url.Action("index", "home", null, "http");

    // TODO: Send url by email
    _repository.SendMail(url);

    return View();
}
