The Halo platform is very customizable so you can get what your looking at done quickly! It also has great reporting capabilities which helps manage all of our campaigns across multiple properties/websites with ease (plus there are many options available!). There really isn't anything I dislike about this tool yet but maybe if we were using more advanced features like micro-segments then adding new data sources could be an issue as well? We've been able use their campaign management software since 2015 without any issues or problems from us being customers nor them having support questions when something went wrong internally that they had no way fix themselves aside form waiting days until someone else did - just awesome service overall!! Customer experience & conversion rates have gone up through implementing tools such as Salesforce Data Studio integration plus custom dashboards along side other internal initiatives within our team -.
