OuterSignal researches two kinds of people: customers and prospects.
Customers are people who have placed an order. When a customer places an order through your Shopify store (or via API or CSV upload), OuterSignal automatically searches public databases and web sources to enrich that customer's profile with additional information such as occupation, interests, income indicators, family status, and more. This data is then pushed back to your systems (Shopify tags, Klaviyo segments, etc.) for immediate use in marketing campaigns.
Prospects are people who gave you an email but haven't bought yet. They're only researched when you choose to: upload a CSV of emails with Research prospects turned on, turn on research for new Shopify sign-ups, or pick Klaviyo lists to research. Each prospect gets the same research and a persona, and appears on your Signal Feed's Prospects tab, separate from your customers. If a prospect later orders, they move to Customers with their research intact and no new charge.
Customer research and prospect research are completely separate uploads, charged separately. Customers are charged at $0.03 per customer. Prospects are charged at $0.03 for each prospect we successfully research, on every plan, including Scale.
