What are Email Headers?

Email headers are like the hidden backstage of an email. They contain important information about the email’s sender, recipient, subject, date, email authentication validation status for your emails, deliverability and alignment issues, etc. Although you usually can’t see them in your email client, they play a crucial role in how emails are delivered. 

While the raw file for your email headers can be difficult to read, our Email Header Analyzer tool parses your email headers in a human-readable format that helps you easily read and understand this information.

Our online email header analyzer helps you detect, analyze and investigate your email headers for compliance with authentication protocols. This header analysis tool helps you troubleshoot email issues faster and without any hassle, through a quick and accurate examination of your email headers.

How does an Email Header Analyzer work?

PowerDMARC’s email header analyzer tool examines the header section of an email to extract and analyze various details about the message. The header section of an email contains valuable information about the message’s origin, routing, and other metadata.

Here’s a general overview of how our email header analyzer works:

  • Header Extraction

    The email header analyzer starts by extracting the header section from the email. This section is typically hidden from the recipient and contains a series of fields with specific information.

  • Parsing and Decoding

    The email header analyzer parses the header content, decoding any encoded or formatted data, such as base64 or MIME encoding. This step is necessary to make the header information readable and understandable.

  • Field Analysis

    Each field in the header is examined individually to gather relevant information. Some common fields that are typically analyzed include the sender’s email address, name, subject, date the email was sent and received, etc.

  • IP Address Extraction

    The analyzer identifies and extracts IP addresses mentioned in the header. These IP addresses can help determine the source of the email, although they can be easily spoofed or hidden using various techniques.

  • SPF, DKIM, and DMARC Analysis

    Our email header analyzer checks for Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) records. These authentication mechanisms help validate the email’s origin and ensure it hasn’t been tampered with during transit.

  • Output and Analysis

    Finally, the analyzer presents the gathered information in a readable format, making it easier for users to interpret and understand the email’s origin, potential authenticity, and other relevant details.
