Yes, one way is to use GenServer.cast/handle_cast. One problem with that is that is gives no guarantees of the destination being there or the message arriving as it literally uses :erlang.send internally. For more safety you could use GenServer.call/handle_call and return the reply :ok. NB that this is doing a synchronous call with all that it costs but you will at least be certain the message has arrived and has been processed.
It’s all a matter of deciding what you need/want and are willing to pay for it. TANSTAAFL
