Klaviyo
Klaviyo is an email and SMS marketing platform. On Shopify it collects subscribers through embedded forms or its own endpoints, syncs storefront events, and runs flows such as back-in-stock and abandoned browse. A theme's contact with it is normally a form target or an embed identifier rather than a data model of its own.

How We've Used It
Signup capture is the recurring one. A footer band or a landing section renders our markup, our field states and our validation copy, and hands the submission to the vendor rather than to Shopify's customer endpoint, so the list stays where the marketing team works. Keeping our own markup around the vendor's target is deliberate: these bands carry brand type and spacing that an externally styled form rarely matches. Back-in-stock is the other pattern — a product page exposes the variant a shopper is looking at and the vendor's flow takes it from there.

Our Role
Integration. We build and place the capture UI and hand the submission over; the list, the flows and the sending are the vendor's.
