## Why Monitor Resend?

When your email provider is unreachable, nothing on your site looks broken. Pages load, forms submit, and the emails your users are waiting for simply never arrive. Password resets, magic links and verification codes stall, and users assume your product is broken. Watching the Resend API and the routes in your app that send email is how you catch that silent failure.

## What to Monitor

- `api.resend.com` — The Resend API root, a lightweight reachability check that doesn't send anything
- `your-app.com/api/health` — An app health route that confirms your email configuration is present and valid, without sending a real email
- `your-app.com/forgot-password` — The page behind your most important email flow, so the flow itself stays reachable

## What You Should Actually Do

1. Monitor api.resend.com to know when the Resend API stops answering; it's a reachability check and doesn't send email
2. Add an app health route that checks your email configuration (API key present, sending domain set) without sending a real message, and monitor it
3. Monitor the pages behind your critical email flows: sign-up, forgot password, magic link
4. Make sure your code logs failed send calls loudly; graceful handling is right, but silent handling hides outages
5. Route alerts to a channel your support team can see, so 'missing email' tickets can be checked against real data
6. Check resend-status.com during incidents, but remember it can't see your API key, sending domain or DNS records

## Resend's Official Status Page

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

## Takeaway

Email outages are silent: the site works, the emails don't. Resend makes sending simple, but your app still needs a way to know when sends stop going out. A monitor on the API, plus your critical email pages, turns 'I never got the email' from a mystery into an alert.

## Frequently Asked Questions

### Can I monitor Resend without sending test emails?

Yes. A monitor on the Resend API root checks that the API is reachable without sending anything. For your own setup, add a health route in your app that confirms your email configuration is in place. Sending a real email on every check would waste sends and clutter an inbox.

### Will uptime monitoring tell me if emails land in spam?

No. Uptime monitoring tells you whether the API and your email flows are reachable. Deliverability (inbox vs. spam) depends on your sending domain's DNS records, content and reputation, which you check in Resend's dashboard and with deliverability tools.

### Should I monitor my sending domain's DNS?

Deliverability depends on DNS records like SPF and DKIM staying correct, but an HTTP uptime monitor doesn't check DNS records. Recheck them in Resend's dashboard after any DNS change, and treat a sudden rise in 'missing email' tickets as a reason to look.

### How is this different from resend-status.com?

Resend's status page reports platform incidents. Your monitors cover your side: your app's routes, your configuration and the flows your users depend on. Most email problems you'll hit, like a revoked key or a misconfigured domain, never appear on a vendor status page.
