Reviewer scorecard
“The standard for observability instrumentation. Auto-instrument once, send to any backend — Datadog, Grafana, Honeycomb.”
“The API is clean, the React Email integration is brilliant, and deliverability is excellent. Replaced SendGrid in 20 minutes and never looked back.”
“Vendor-agnostic instrumentation prevents lock-in. The ecosystem is mature enough for production.”
“Young company with a smaller scale than SendGrid or Postmark. But the developer experience is so much better that it's worth the risk for startups. Monitor deliverability closely.”
“OpenTelemetry will be to observability what Kubernetes is to orchestration — the universal standard.”
“Building beautiful transactional emails used to be painful. React Email components make it feel like building a web page. Game changer for my client projects.”
