If you want to make sure that your Notifications are firing, navigate to Settings > Realtime Automation & Alerts and then locating the Performance Trigger that you want to monitor. 

At the bottom of each notification, you'll be able to see how many times a particular action was fired and when Naytev last checked your content.

Tip: If you've created a trigger to identify the top 10% of any paid or organic content that you've posted, remember that statistically the trigger will only fire once out of every 10 pieces of content posted.
