Email Header Analyzer – Decode & Trace Email Source

Understanding where an email really came from can help you detect phishing, spam, and fraud attempts. Our Email Header Analyzer tool helps you decode the full email header to reveal IP addresses, mail server hops, timestamps, and authentication results—allowing you to track the email source and analyze delivery issues.

🔍 What Is an Email Header?

An email header contains technical details about the path an email takes from sender to recipient. It includes information such as:

• Sender and recipient email servers
• IP addresses and geolocation

2. Paste it into the Email Header Analyzer text box.
3. Click “Analyze” to instantly decode the header.
4. Review the IP hops, server metadata, and message path details.

This tool helps:
