Send severity-based error alerts using Telegram, email and Google Sheets

Who this template is for

This template is designed for n8n users running workflows in production who need reliable and structured error monitoring, not just basic alerts.

It’s especially useful for: - Automation engineers and developers - Teams running business-critical workflows - Anyone who wants smarter alerting with reduced noise

---

What this workflow does

This workflow acts as a global, severity-based error monitoring system for n8n.

When a linked workflow fails, it automatically: - Classifies the error by severity (Critical, High, Normal) - Routes alerts based on severity level - Sends notifications via Telegram and Email - Logs critical errors for auditing and troubleshooting

This ensures important issues are escalated properly, while avoiding unnecessary alert fatigue.
