How Shopper ID works

Setup

1. Add your store under Sites and choose ecommerce.
2. Install the tag on your store. See Shopify or HTML.
3. Add a Klaviyo destination.

What happens

When a US shopper we recognize visits your store, we send Klaviyo an event called WhoLayer Shopper Identified with their email and the pages they viewed. In Klaviyo, use that event as a flow trigger, for example a browse-abandonment flow.

Plan and costs

Shopper ID with Klaviyo sync is included on the Growth plan and above. Each shopper costs 1 credit the first time they're identified in a calendar month; return visits that month are free.

Use it in flows, not blasts

These shoppers didn't sign up for your list. Send them a relevant, honest message tied to what they browsed, include your business address and a working unsubscribe link (CAN-SPAM requires both), and honor opt-outs right away. See your responsibilities.
