So lately I've been wanting to receive notifications from various projects and rather than setting up a mail server or dealing with mail servers in general, I've started using a local docker container of Ntfy.sh so I can have my own dedicated server for it. I receive notifications if anyone is successful in accessing an internal server or even my external servers. I use it for even just notifying me when a form is submitted through google forms.

It has become an essential part of my workflow, to keep my aware of whats going on, but not overdoing it. One of the features I like the most is I can have it provide an action to take me to a specific page, or if you know the URI, you can have it open up a specific app on your phone when you trigger the action. Urgency can also be set so I can have it identify the ones that I need to pay attention to right away and glance at the others when needed.

I'd be interested to hear what others are using for notifications and how useful they are to you.
