2. PARTIAL orders send the **Add To Cart** event (abandoned carts only; i.e., the order has products)
3. Subscribe Opt-In sends the **Subscribe User** event (if the customer has [opted into marketing](https://help.checkoutchamp.com/funnel-builder/creating-and-editing-funnels-pages/funnel-visualizer-and-page-builder/page-builder-2.0/page-building-tips/creating-a-marketing-opt-in-checkbox))
