Introducing email API benchmarks

Knock has introduced a real-time dashboard for email API benchmarks, providing an objective comparison of email providers such as SendGrid, Resend, and Postmark based on performance metrics like response time and error rate. This initiative aims to fill the gap left by subjective resources, offering data collected from billions of API requests processed annually. The dashboard includes metrics computed using precise quantile calculations and tracks the ratio of error responses, helping users assess provider resilience in time-sensitive scenarios. Providers are ranked by adoption trends and correlated with public incidents for a comprehensive performance overview. Additionally, the platform features modeled pricing curves and a side-by-side comparison tool, allowing users to evaluate costs alongside performance when considering a provider change. Knock plans to expand the dashboard's metrics, including deliverability and time-to-inbox, and encourages community feedback to enhance this resource.
