The most useful part of filtering on contact data is that you can filter for verified emails or specific phone numbers, such as Mobile/Direct/Office which makes the difference compared to other tools, but I would mention also the extremely broad list of technologies that you can filter for, which is a feature that works uniquely good compared to other similar tools. The interface is among the most user friendly ones, as it takes no more than one hour to discover most of its capabilities and even figure how you can best leverage its filtering features.
