Upstack Data is a server-side tracking and identity app for Shopify. It uses our network of 750M+ identified consumers to restore lost click and device IDs, capture conversion data blocked by iOS and ad blockers, and send first-party CAPI data to Meta, Google, Klaviyo, TikTok, Pinterest and others via Conversion API. With higher EMQ Scores and match rates, Meta and other ad platforms target new customers more efficiently.

Go beyond the basics with the Klaviyo marketing app. New stores get a guided setup — sign-up form, welcome email, and abandoned-checkout flow — without leaving Shopify Admin. Unify data from 350+ integrations and boost marketing performance with campaigns, smart segmentation, and automated workflows from Klaviyo’s AI Agents. Over 117k brands use Klaviyo and Shopify to grow faster with personalized emails, SMS, WhatsApp messages, and marketing automation tools that turn browsers into buyers.

Inbox puts an AI-powered sales associate on your storefront. Buyers can ask questions and get help finding the right products from your catalog. When buyers sign in with Shop, your Inbox agent can personalize replies using their preferences and purchase history from across Shopify. Run Inbox with or without the agent. Inbox learns from your catalog, policies, and store content while you control its tone, style, and rules.
