How can I know if the client has received a message?

I’m using a lot the MyApp.Endpoint.broadcas/3 method for a phoenix project and I would like to know if there is a way to know if the client receives the message?

That function broadcasts to a process, and it is done async, which tends to be most useful since there can be a lot of processes listening. If you want to know if they receive it then just have them send a message back, same as with any other process on the EVM. :slight_smile:
