The support team is incredible, it's easy to get assistance from them through phone or email (they do not require you post all of your problems). I have never had any issues with this tool! It has been very helpful when creating reports for our marketing efforts by allowing us access at various levels in order that we can choose what information they collect most efficiently as well give more granular control over certain areas like demographics/interests etc., We are using its geo-targeting features within emails campaigns so far but haven't found many other ways yet where i wish there were some customization options available beyond just targetting countries - however these could be added easily if anyone was looking into doing exactly whats described here which would provide significant value compared against similar tools out tharere! Highly recommended especially now since their rates went up considerably after Google discontinued interest targeting API feature last year!! This software allows me create multiple customized profiles per customer / user without having separate contact lists created manually.
