Email Header Analyzer

An email header includes, for example:

• Sender's and recipient's email addresses
• The date and time the email was sent
• The email servers involved in the delivery process
• The subject line of the message

Go to your Google Mail account and open an email. Find “More” (3 vertical dots), and choose “Show original.”

Go to your Outlook email account and open an email. Find “More actions” (3 horizontal dots), and choose “View message source.”

Go to your Yahoo Mail account and open an email. Find “More actions” (3 horizontal dots), and choose “View raw message.”

Email header analysis looks at the technical details in an email header such as the sender IP, server hops, and authentication results to identify misconfigurations or suspicious activity.

Email investigation takes a broader view. It uses header analysis as a starting point but also examines message content, compliance indicators, and deliverability factors to uncover phishing, fraud, or recurring issues.

EasyDMARC’s tool combines both approaches, providing quick header checks along with a deeper investigation for complete visibility into email security and performance.
