I like how easy it was setup my account just by providing an API key which allowed me access quickly without having any prior knowledge of coding or development skills required! The ability to create multiple versions/versions at once makes this very powerful tool even more useful in our daily operations as we are able to easily switch between them when needed (or not). It's great being able to pull up historical analytics from previous months so there isn't much downtime during new month start ups - especially if using different dates than what already has been used previously within other campaigns etc..
