The data is accurate, comprehensive & most importantly timely! It's very easy to use as well since it has all of our internal marketing channels in one place (email campaigns/social media posts etc.) We've also been able solve some customer service issues with this tool by being more organized internally about tracking KPIs within each channel for every campaign we run so that they can see what works best across multiple platforms at once - which helps us keep track if any changes need be made or implemented quickly before an issue gets out into production too much later than planned / desired..
I wish there was something like Datalife where you could add your own custom fields but other then those few things everything else looks great :).
