Do I need deliverability monitoring for critical notifications?

Yes — if the notifications are critical, you should absolutely have deliverability monitoring.
Why it matters:
- Critical messages can fail silently due to spam filtering, throttling, bounces, suppression lists, DNS/auth issues, or provider outages.
- Without monitoring, you may think messages were sent when they never reached users.
- For things like password resets, fraud alerts, security notices, OTPs, billing, or outage alerts, missed delivery can become a support, compliance, or trust issue.
What to monitor:
- Bounce and complaint rates
- Spam placement / inboxing
- Delivery latency
- Provider/API errors
- Suppression list growth
- Domain authentication health (SPF, DKIM, DMARC)
- Webhook/event failures from the email/SMS provider
- Send volume anomalies
- Open/click rates only as secondary signals, not proof of delivery
Best practices:
- Set alerts for spikes in bounces, complaints, and API failures
- Use multiple channels for truly critical alerts if possible
- Keep a fallback provider or retry strategy
- Verify domain and sender reputation regularly
- Log message IDs end-to-end so you can trace failures
- Test deliverability continuously with seed accounts or monitoring tools
If you want, I can also suggest a minimal monitoring setup for email, SMS, or push notifications.
