How Goldcast scaled event orchestration to millions using Temporal

Goldcast, a B2B event marketing platform, has transformed its operational infrastructure by integrating Temporal Workflows to enhance the reliability and scalability of its email delivery and event duplication processes. Initially an experimental addition, Temporal quickly became central to Goldcast's ability to manage the complexities of sending hundreds of thousands of emails and orchestrating event duplications with rollback-safe and asynchronous phases. This integration has resulted in significant improvements, such as a 99.9% success rate for large email sends and a 99.8% success rate for event duplication, while reducing manual intervention and operational stress. The platform's adoption of Temporal has also streamlined workflows, replacing fragile, bespoke logic with robust, observable processes, allowing the engineering team to focus more on building rather than firefighting. Goldcast plans to further leverage Temporal for additional services, contributing back to the open-source community with their developed patterns and utilities, thus ensuring a dependable foundation for their operations even during peak stress periods.
