I like how well it integrates our email marketing system as we can see all of my contacts who opened an e-mail from me or clicked through one of those links that are sent out automatically for example when someone signs up via social media integration.
It is very easy to use but sometimes there's just nothing you could do about certain issues where your contact would rather hear directly than read something they've already seen before (like a message saying "Hi this looks good" -_-) but if thats not your problem then its great! The main issue was integrating into other platforms so people dont have to go back & forth between different interfaces to get things done which has been resolved since bizzy helped us integrate them together. Also being able to track every single lead & user profile without having to manually add data each time makes tracking much.
