Description

🛠 Website Downtime Monitoring with Scheduled Checks and Email Alerts

Easily monitor your website uptime and receive instant email alerts when it becomes unreachable — using this no-code template powered by n8n, a free and flexible workflow automation tool.

This ready-to-use workflow periodically checks your website’s status and sends an alert email if it’s down.

⚙️ How it Works

• Schedule Website Check
  Triggers the workflow at regular intervals (e.g., every 8 hours by default).

• Check Website Status
  Sends an HTTP GET request to your site.

• Evaluate Response
  Determines if the site is reachable (expects HTTP status 200).

• Send Downtime Alert
  If the site is down, an alert email is sent to the specified address.

🔧 Steps to Customize

1. HTTP Request Node

Replace https://yourdomain.com with your actual website URL.

2. Send Email Node

Update the To Email and From Email fields with your addresses.

3. Adjust Monitoring Frequency

Modify the Schedule Trigger node to run every 5 minutes, hourly, or as needed.

✅ SMTP Configuration Instructions

Before emails can be sent, you need to configure SMTP credentials in n8n.

📨 Option 1: Gmail SMTP Setup

> Note: Gmail requires App Passwords (not your regular Gmail password) and 2FA to be enabled.

Steps:

1. Go to Google Account Security Settings.
2. Enable 2-Step Verification.
3. Go to App Passwords.
4. Create a new app password (choose Mail and Other, name it n8n).
5. In n8n:
   • Go to Credentials → Create New → SMTP.
   • Use the following values:
     • Host: smtp.gmail.com
     • Port: 465 (SSL) or 587 (TLS)
     • User: your Gmail address (e.g., you@gmail.com)
     • Password: the App Password you generated

✉️ Option 2: Generic SMTP Setup

Use this if you’re using your hosting provider’s or business email SMTP server.

Example Values:

• Host: smtp.yourdomain.com or provider-specific (e.g., smtp.sendgrid.net)
• Port: 587 (TLS) or 465 (SSL)
• User: your email address (e.g., alerts@yourdomain.com)
• Password: your email/SMTP password
• Secure: Yes (if using 465 or TLS-enabled 587)

Then in the workflow’s Send Email node, select the SMTP credentials you created.

📌 Requirements

• A running instance of n8n (self-hosted or n8n.cloud)
• SMTP credentials configured in n8n for email delivery
• Basic familiarity with the n8n visual editor

🧠 Pro Tips

• Rename Nodes: Use clear, descriptive names for maintainability.
• Sticky Notes: Use stickies on the canvas to help explain logic for others.
• Expand Alerts: Integrate with Slack, Discord, or Telegram for multi-channel alerts.
