## Why Monitor SendGrid?

Email is invisible when it fails. A password reset that never arrives, a receipt that doesn't send, a notification stuck in a queue — none of these throw an error your users see. They just silently don't happen. When SendGrid has API issues or deliverability problems, your transactional email breaks without a single visible error.

## What to Monitor

- `your-app.com/api/email-health` — App endpoint that checks SendGrid API reachability
- `your-app.com/api/webhooks/sendgrid` — Your event webhook receiver for delivery/bounce events
- `status.sendgrid.com` — SendGrid's status for platform-level incidents

## What You Should Actually Do

1. Create an app endpoint that checks SendGrid API reachability and monitor it externally
2. Monitor your SendGrid event webhook receiver — a drop in delivery events signals a delivery problem even when sends 'succeed'
3. Watch for spikes in bounces and deferrals, which indicate deliverability issues distinct from API outages
4. Track SendGrid's status page for platform-level incidents
5. Use a non-email alert channel (Telegram, webhook) so SendGrid outages don't suppress your own alerts

## SendGrid's Official Status Page

SendGrid publishes real-time status at https://status.sendgrid.com. Your own monitor complements it by catching connection-level issues, often before the status page updates.

## Takeaway

Email's biggest danger is that it fails silently. SendGrid accepting your request isn't the same as the email arriving, and there's no error your users see — just a reset, receipt, or verification that never comes. Monitoring the API and your delivery webhooks turns invisible email failures into immediate alerts.

## Frequently Asked Questions

### Can I monitor whether my emails are actually delivered?

Directly testing end-to-end delivery is hard, but you can monitor SendGrid's API reachability and track your event webhook for delivery, bounce, and deferral events. A drop in delivery events or a spike in bounces signals a delivery problem.

### Why does SendGrid accept my email but not deliver it?

A 202 Accepted response means SendGrid queued your message, not that it was delivered. Delivery can fail due to deferrals, bounces, recipient server issues, or platform problems. Monitor SendGrid's event webhook to see what happens after acceptance.

### What should I monitor for transactional email reliability?

Monitor an app endpoint that confirms SendGrid API reachability, and monitor your event webhook receiver so you know delivery callbacks are arriving. Together these catch both API outages and delivery failures.

### How is this different from status.sendgrid.com?

SendGrid's status page reports platform-wide incidents. Your monitor checks how SendGrid works for YOUR app — whether your sends succeed and your delivery events arrive. Account-specific issues like reputation problems, rate limits, or suppressions won't appear on the platform status page.
