We've been using them for a couple of years. On the list of "best ROI" considering all the marketing we do they rank in the top 3 for us.

I love the ability to see the contacts and associated company prior to the purchase. The integration with HubSpot is great and super helpful! As we are still in the process of figuring out what works best for us, Jake & Claire have been super helpful at walking us through the tool and answering questions as well as giving us feedback on our campaigns.

The database coupled with the email automation makes this tool so easy to use and really efficient.
