Email Investigation

EasyDMARC's Email Investigate tool is based on peer-sending technology. You get a unique inbox address and send an email from your sending domain. This action triggers the tool to analyze your email headers and return detailed information about SPF, DKIM, and DMARC records. It also reveals your domain's DMARC policy and retrieves the configuration guide for source authentication setup.

Here's how to use Email Investigation:

• Send a single email (content doesn't matter) to the address provided by the Email Investigation tool.
• The email will appear in the Email Investigation section of your EasyDMARC account labeled as "Compliant" or "Non-compliant."
• Open the email for a more detailed breakdown of each email sending source and its current status.
• Adjust your domain setup where necessary by following the given instructions.

Emails consist of 2 main parts–the header and the body. The former contains the metadata for the email, while the latter is the contents of your email.

Email header contains:

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

Analyzing an email header lets you gather critical information about the email's source, path, and sending servers. Email header analysis is a crucial 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. These protocols use cryptographic methods to authenticate the sender's identity. Thus, analyzing the email header gives a lot of information about whether the email passed or failed the authentication checks.

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 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.

With the help of our smart feature, you can quickly identify and solve problems with your email authentication and ensure that your emails are delivered securely and reliably.

DMARC Aggregate reports are, by default, sent once in 24 hours. You'll have to wait before you get the first one after deploying the DMARC record in your DNS. Our Email Investigation tool helps you check specific sending source configurations one at a time while you wait.

Email Investigate is also irreplaceable when you're making changes to or troubleshooting your email sending source configurations even after you've received the report. Read this article to learn more.
