Clarification on Sending Emails Asynchronously
Hey Folks,
Quick question, while implementing email functionality into my Phoenix App I came across multiple sources that claim:
Opposite to some stacks, sending emails, talking to third party apps, etc in Elixir do not block or interfere with other requests, so you should resort to async emails only when necessary.
This seems so foreign to me, coming from other platforms like Rails. Can someone briefly explain why this is the case in Elixir and what specific scenarios require async emails/calls? I love how responsive Phoenix and LiveView Apps are and would hate to loose that with a call that blocks the UI.
Thanks,
Scott

It goes even further than that. Elixir’s processes are not only OS threads; you can still have tens of thousands of processes and parts of them might be stuck (and that count can be much more than the amount of CPU cores) but the rest will still continue running.
