Email headers are an essential part of every email you send or receive. They contain crucial information about the email's origin, pathway, and delivery. Understanding email headers is vital, especially when it comes to tracking, troubleshooting, and verifying the authenticity of emails. In this article, we will explore why email headers matter and how you can access them.

What are Email Headers?

Email headers are hidden technical details that accompany every email communication. When you send or receive an email, the email headers provide a detailed record of the email's journey, including the sender's and recipient's information, the servers it passed through, and timestamps. While email clients usually hide the headers by default, you can view them to gather valuable information about the email's source and path.

Why Do Email Headers Matter?

Email headers matter for various reasons:

  • Tracking: Email headers allow you to track the route an email took from the sender to the recipient. This information is helpful in identifying potential delivery issues or exploring delays.
  • Email Authentication: Email headers contain technical data that helps verify the authenticity of the email. This authentication data includes SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance).
  • SPAM Analysis: Email headers provide valuable information for analyzing and identifying SPAM or phishing emails. They can reveal suspicious servers or spoofed sender addresses.
  • Troubleshooting: When encountering issues with email delivery or unusual behavior, email headers can assist in troubleshooting problems. They can reveal errors, server responses, and potential misconfigurations.

How to Access Email Headers?

The process of accessing email headers varies depending on the email client or service provider you use. Here are some general steps to access email headers in popular email clients and webmail services:

  1. Gmail: Open the email in Gmail, click on the three-dot menu icon at the top right corner of the email, and select "Show Original." The email headers will appear in a new tab.
  2. Outlook: Open the email in Outlook, click on the three-dot menu icon ("More actions") in the top toolbar, and select "View message details." The email headers will be displayed below the email content.
  3. Yahoo Mail: Open the email in Yahoo Mail, click on the three-dot menu icon at the top right corner, and choose "View Raw Message." The headers will be shown below the email.
  4. Apple Mail: Open the email in Apple Mail, go to "View" in the menu bar, and select "Message," then choose "All Headers." The email headers will be displayed below the email.

Note that these steps are general guidelines, and the exact process might vary slightly depending on the email client or service provider you are using. If you are using a different email client, consult their documentation or support resources to find out how to access email headers.

Conclusion

Understanding email headers is crucial for various reasons, including tracking, email authentication, SPAM analysis, and troubleshooting. By accessing email headers, you can gather valuable information about the email's path, origin, and potential issues.
