Stamped & KnoCommerce | What Every Marketer Needs To Know About Zero Party Data [Webinar]
Jeremiah Prummer has created a product that's close to our hearts at Stamped: KnoCommerce. KnoCommerce helps Shopify merchants fill in the gaps of their missing customer data by asking important questions at the right moment. Unlike other attribution or checkout survey solutions, Kno gives you templates for fast setup, and helps you use and understand your data in real-time. In this webinar, Jeremiah, CEO of KnoCommerce, teaches us the fundamentals of zero-party data and some best practices to implement right away. We also explore key moments of the buying journey where motivation is high and customers are likely to share their data, specifically immediately post-checkout. Stamped Checkout Reviews & KnoCommerce Post Purchase Surveys maximize the zero-party data collected during transaction.
