An exciting feature in BuzzBuilder is the Follow-Up Tasks, which help you organize your follow-up efforts in tandem with email campaigns that are sending. On this list, it will show all contacts you are emailing, and allow you to sort them by their interest level--this way, you can focus on your best prospects first. This page also tracks each attempt you've made to reach your contacts, how many conversations you've had, and the number of successful outcomes (such as an appointment). This way, you can understand your statistics and ratios.
Below is a video that explains how to leverage this powerful feature.
