Until is very easy set up from scratch through our team members experience and support teams are excellent throughout all stages of integration as well! We had issues at first but After getting help they were able resolve it quickly & accurately.
If I have any questions after initial setup we don't get push notifications like many other platforms so if there's something urgent then it takes longer than expected (not too big an issue). The main benefit has been being one platform which helps us manage content creation better by having access to everything within until rather than creating separate emails etc.
