What Is Email Investigation?
Email investigation is the process of analyzing email data to uncover issues related to fraud, phishing, data breaches, and email deliverability. A key part of this process is email header analysis, which provides visibility into the sender’s identity, message authentication (SPF, DKIM, and DMARC), delivery path, and any misconfigurations that may affect inbox placement.
With EasyDMARC’s advanced email investigation tool, however, you can do more than just analyze email headers. Our premium solution also shows DNS record results, blacklist status, SpamAssassin scores, message structure and content, compliance indicators (like unsubscribe links), and even an email preview to see how your message is displayed to recipients.
Whether you're troubleshooting delivery issues or investigating suspicious emails, our DMARC header analyzer helps you quickly pinpoint problems, which can improve both your email security posture and deliverability performance. Even users without deep technical expertise can gain insights and take actionable steps to ensure authenticated, compliant, and successfully delivered emails.
How Does Email Investigation Work?
EasyDMARC's email investigation tool works in two ways. You can either send an email from your sending domain to a unique inbox address, or you can upload an EML file of your email header. This action triggers the tool to analyze your email header and diagnose issues with email deliverability and security.
Here's a step-by-step guide on how to use EasyDMARC's email investigation tool:
For Registered (Features-Enable) Users
Choose Your Input Method
After signing in to your EasyDMARC account, send an email to the unique address provided in the platform, or upload an EML file of the email header you want to have analyzed. Alternatively, you can copy the email header or the entire email and paste the contents into the field provided.
Get A Full Analysis
Once we receive your email, the tool automatically performs a full email header analysis and displays results across multiple tabs, including:
- Overview
- Readable version of the email header
- Email preview
- Email content
- Compliance
- Authentication status - SPF, DKIM, DMARC, and BIMI results
- Blacklist status
View Historical Results
Every test you perform is automatically saved in your personal dashboard. You can view your full history at any time, unless you choose to delete individual entries.
For Public (Non-Registered) Users
Choose Your Input Method
Firstly, send an email to the publicly available test address displayed on the tool page, or upload the EML file of the email header you want to have analyzed. Alternatively, you can copy the email header or the entire email and paste the contents into the field provided.
Get Limited Results
You’ll receive the latest test results, including email header analysis, SPF, DKIM, and DMARC authentication status, and blacklist checks.
No Historical Access
Public users can run unlimited tests, but only the most recent result is available—test history is not saved, and some tabs (like Overview, Content, and Compliance) are restricted.
What is Email Header Analysis?
An email header analysis is the process of examining the technical metadata in an email header to understand how the email was sent, where it came from, and whether it can be trusted. Emails consist of a header and the body. The former contains the metadata for the email, while the latter contains the email's contents.
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
Email header analysis is an important technique for understanding the technical details of email communication and ensuring email security and authenticity. Email header analysis is particularly important for implementing email authentication protocols such as SPF, DKIM, and DMARC because an email header can reveal a lot of information about whether the email passed or failed authentication checks.

How to Detect and Troubleshoot Email Issues?
An email header analysis is one of the best ways to detect and troubleshoot email issues. It can help to identify the source of spam and phishing emails, detect domain spoofing attempts, and troubleshoot email delivery problems.
EasyDMARC's email investigation tool analyzes the email headers and provides detailed information on the sending source statuses for SPF, DKIM, and DMARC. Our tool can also determine whether the email passed or failed the authentication checks and identify any potential issues.
If the email fails authentication, the tool will provide details and reasons for the authentication failure. This information can help you troubleshoot the problem and take the necessary steps to fix it, such as updating your SPF or DKIM records.
