The ability to track leads from website visits or other sources is very powerful in terms of lead qualification. I can see where my clients are coming from when they visit our site. Nothing so far that has been bad about realvue as it's gotten out there with me quickly enough. There are some features that really have not come into play yet (we do work primarily B2B). Keep up with this product! We need more than just an email capture solution - we also need analytics and data reports. This gives us all these things.
