Working with David and the Third Arm Marketing Team over the past seven years, and launching our new BigCommerce site with them, we’ve seen our conversion rate more than double and our web sales increase at an even larger rate. The MailChimp integration has been more effective than we even hoped for and keeps our current customers coming back! Highly recommended!
