Resend Prometheus Monitoring: Alert on Email Bounces in Grafana

If you are looking for Resend Prometheus monitoring, Resend Grafana alerts, or a way to alert on email bounces, that is exactly what

The current release is v0.2.1.

What I still want to add

The next useful feature is optional Resend API reconciliation.

Webhook-only mode is intentionally simple, but an API key could enable:

• backfilling recent events after exporter downtime


• checking whether required Resend webhook events are configured


• enriching sparse webhook events


• exposing configuration health metrics

I also want to add delivery-delay histograms, bounce-type breakdowns, and first-class PrometheusRule support in the Helm chart.

The larger point

This project is small, but the pattern matters.

If a user-facing side effect can fail after your application says "success", it deserves observability.

Transactional email is not background noise. It is production behavior.

And if production behavior breaks, I want the same boring machinery that watches everything else to notice.

That is all resend-exporter really does.

It makes email delivery failures page-shaped.
