What is Spillmark?

Spillmark is a specialized online analytics and experimentation tool tailored for Amazon sellers who use Meta ads. This innovative platform seamlessly consolidates data from Amazon Seller Central, Amazon Ads, Meta, and optionally Shopify, enabling users to evaluate their sales performance, expenses, fees, advertising costs, and the overall profitability of their channels through a variety of connections and report imports. Sellers can implement geographic holdout tests, which involve suspending Meta ads in specific locations, to analyze Amazon sales and gauge the incremental effects of their advertising strategies. The results are provided with confidence intervals and thorough explanations of the methodologies used, along with dashboards, alerts, and documentation of test designs. Importantly, access to linked accounts is strictly read-only, ensuring that no campaigns are altered without the seller's explicit approval. Furthermore, Spillmark includes an MCP server and REST API, facilitating integration with assistants and scripts to improve its functionality. Currently, the platform is testing brand-level measurement and customized recommendations in a private beta phase. Its Starter package allows users to conduct one active holdout test and receive notifications, while the Growth package includes unlimited tests, live account connections when available, and personalized Amazon PPC tests, addressing the dynamic requirements of sellers as they expand their businesses. Through its cutting-edge features and intuitive design, Spillmark is dedicated to refining the marketing approaches of Amazon sellers and enhancing their overall success. This commitment to innovation positions Spillmark as a vital resource in the competitive landscape of online selling.
