About Email API benchmarks
Today we're releasing email API benchmarks, a real-time dashboard of email provider performance to help you compare and choose. The dashboard is powered by the billions of API requests Knock sends to downstream providers like SendGrid, Resend, Postmark, and more. We've aggregated this data to highlight important metrics (like response time and error rate) to help you compare email providers, not based on hype, but on their real-world performance data.
