RECLAIM helps you send out more abandoned cart and product flows. The problem it's solving is that today, only LOGGED IN USERS can receive these flows.
Reclaim expands the audience of recipients to two net-new audiences:
1) Visitors who are on your list, but on a different device and
2) Visitors who WE have the opt-in for (via GROW), but you don't yet
Reclaim will trigger an abandoned cart, product, or category flow based on these visitors' ongoing behavior on your website.
