We have worked with them since 2015 and they have been great! We started with a pretty basic email marketing service (think Facebook ads) and now we are utilizing their complete lead generation and CRM tool to help us identify potential customers and make the best decisions about when to contact them. It has taken over a year and hundreds of thousands of dollars to get here, but now that we're there, we are thrilled with how easy it is to use and how it is helping us identify people that would otherwise go unnoticed. The ROI is extremely high and our business is growing. I recommend anyone looking to get started with email marketing to give them a try - you won't regret it!
