assert_email_delivered_with has verbose failure output

  defp flunk_attributes_do_not_match(params_given, params_received) do
    """
    The parameters given do not match.

      Parameters given:

        #{inspect(params_given)}

      Email received:

        #{inspect(params_received)}
    """
  end

When you encounter an email failure that uses the helper above, the "Email received:" portion of the failure consumes a lot of space in the error message. Maybe only "Parameters given" should be shown by default and advanced users can provide an additional argument to request verbose output?
