Instacart has developed a multi-tenant marketing platform to enable personalized marketing capabilities for its white-label Storefront Pro retailers. This platform extends existing marketing automation infrastructure by introducing per-retailer workspaces within a third-party vendor, ensuring data isolation and brand integrity. Key components include Instacart tooling for retailers, a Campaigns Engine for audience evaluation and personalization, a stream consumer and batching layer to improve throughput and API efficiency, and the Instacart CRM Service for message preparation and routing. The system addresses scale challenges through batching and horizontal scaling of asynchronous workers, and includes operational considerations for domain configuration and automated IP warming for email deliverability.
