Send shoppers to Klaviyo

1. In Klaviyo, go to Settings, then API keys, and create a private key with write access to Events and Profiles.
2. In WhoLayer, open Destinations, choose Klaviyo, and paste the key.
3. Click Send test, then look for the WhoLayer Shopper Identified metric in Klaviyo.
4. Build a flow triggered by that metric. Browse-abandonment and cart-reminder flows work best.

The event includes the shopper's email, name when known, and the pages they viewed, so you can personalize the message.
