About

Spillmark is a web-based marketing analytics and experimentation product for Amazon sellers using Meta ads. It combines data from Amazon Seller Central, Amazon Ads, Meta, and optionally Shopify through account connections or report imports to analyze sales, costs, fees, ad spend, and channel profit. Sellers can design and run geographic holdout tests that pause Meta ads in selected regions, then compare Amazon sales to estimate advertising's incremental effect. Results include uncertainty ranges and explanations of the calculations, alongside dashboards, alerts, and records of test designs. Connected-account access is read-only; the product does not change campaigns without seller approval. Spillmark also provides an MCP server and REST API for assistants and scripts. Brand-level measurement and recommendations are in private beta. Starter includes one active holdout test and alerts; Growth includes unlimited tests, live account connections when available, and branded Amazon PPC tests.

About
