I like that they have an app which makes this process very simple! It also allows me as admin user access so i dont need another person with permissions (which would be required otherwise).
Also being able to track notifications by day/month helps when trying figure out what works best or doesn't work at all from month 1 - 4 months later etc.. They are always improving their product but overall its been great since we started using them over 2 years ago now!! The benefits include tracking our campaigns performance easily without having developers involved within my team who could potentially mess things upp if not careful enough.
