How do I get mail notifications without opening mail?

The fact that I need to launch the Mail.app app, either via launchpad/spotlight or via Finder, to initiate the fetch mail fetch service is a bit un-Apple-y.

I know that I can run a script (or add Mail.app to Login items in System Preferences) which launches mail whenever I boot/re-boot macOS and close the inbox-window. But I'm wondering if there is a daemon/service which I can run which checks for mail without actually opening the Mail.app

All I am looking is a solution which is already implemented in mobile OS where the default mail application receives mail even when the "app" is not running in background but the service (daemon in macOS terms) is.

Thanks in advance. :)

P.S. I'm sorry about tagging this post in "macOS Mojave", but I couldn't find any appropriate topic.
