I like how easy it was for me to set up, as well as having all of my contacts already in there so they were ready when we went live! The customer service has been great too - helpful throughout every step of our launch process from helping us choose an ad format (which one works best with our site) through answering questions about what features are available. They have also had some minor glitches here or there which caused delays but their team fixed them quickly. We're launching at this time because we've seen such good results using these ads previously.
