The best thing about this product is that it has all of my favorite features in one place. I love how easy it is to use and set up so that I don't have tons of emails going out with different things in them or having multiple tracking codes everywhere! Not much at this point since we are just using it as part of our CRM system but if you're looking into something like this then make sure you test everything thoroughly before making any final decisions. We've been able to get some great data for our sales team. They were unsure what they should do when interacting with customers online vs offline so now they know exactly where their leads come from.
