Unraveling the Enigma of Email Headers
What is an Email Header?
Every email is composed of two parts: the body, which is what we usually interact with, and the email header, a section of essential data that most users don’t even notice. An email header is a source of useful data that comes with the body of each email message, containing a wealth of information about the sender, the recipient, the date, and more.
Even though the email header might seem irrelevant to the average user, it’s a goldmine for those who know how to analyze and interpret its contents. Email marketers, cybersecurity experts, and IT personnel use this hidden data to trace the path of an email, detect spam or phishing attempts, and understand more about the email’s sender and its journey through the internet.
Decoding the Email Header: What Does it Contain?
An email header is like a log book, tracking the email’s journey from sender to recipient. This information is critical for various reasons, including verifying the sender’s information, tracing the email’s path, and identifying any red flags indicating spam or malicious content.
Here’s a brief rundown of the primary components useful data that an email header analysis can reveal:
Return-Path: This is the address where bounce-backs get sent if the email can’t be delivered. It’s crucial for marketers to keep their return path clean to avoid being marked as spam.
Received: These lines are the IP addresses involved in the transmission of the mail. They are key to tracing the email’s path across the internet.
Message-ID: This is a unique identifier for each message, like a fingerprint. It can be used to track or locate an individual email in a sea of data.
From: The sender’s email address. This could be different from the return path, particularly in cases of spam or phishing emails.
Subject: The email’s subject line.
Date: The date and time when the message was sent.
To: The email address of the next mail recipient.
MIME-Version: It stands for “Multipurpose Internet Mail Extensions.” It’s a way of identifying files in internet emails by their MIME version and type.
Content-Type: This indicates the media type or subject of the message or its attachments.
Authentication Results: These headers verify the identity of the sender.
The above is not an exhaustive list but gives an overview of the significant elements in an email message header here. Different tools can help decode and analyze these aspects, including the message header analyzer and the email header analyzer tool.
The Power of an Email Header Analyzer Tool
An email message header analyzer or tool is a piece of software designed to decode the often complex and confusing data in an email header, turning it into a more digestible format. This tool is used to parse the email headers and convert them into a human-readable form, which helps understand the details of the email header better.
To use this tool, you typically have to copy the entire email header text and paste it into a text box in the tool. The analyzer then takes this input and presents you with a structured output detailing the different elements in the email header text, their significance, and any anomalies that might be worth noting.
Email header analyzers are beneficial for several reasons. First, they provide a quick and efficient way to decode an email header without needing advanced technical knowledge. Second, they can help identify potential red flags in an email header that might suggest spam or phishing. Third, for marketers, they offer insights into email delivery paths, which can help optimize delivery rates and overall campaign performance.
Let’s take a closer look at an example of how you can use an email header analyzer tool to decode an email header.
Decoding an Email Header: A Step-by-step Example
Imagine you have a Gmail account, and you receive an email that you want to analyze. Here is a step-by-step guide to using an email header analyzer tool to do this:
- Open the Email: Open the email in your Gmail account.
- Access the Original Message: Click on the three vertical dots in the upper right corner of the email window. A drop-down menu will appear. Click on “Show original.”
- Copy the Email Header: A new window will open displaying the original message with the email header and the body of the email. Highlight the entire block of text in the “header” section and copy it (Ctrl+C for Windows or Command+C for Mac).
- Paste into the Analyzer Tool: Open your email header analyzer tool in another browser tab or window. Locate the text box where you input the email header data. Paste (Ctrl+V for Windows or Command+V for Mac) the copied header into this box.
- Analyze the Header: Click the “Analyze” button or equivalent to start the analysis. The tool will then present the analyzed information.
- Review the Results: Look over the displayed details and note down any relevant findings. You might see data such as the sender’s IP location, the message’s trace, and any received SPF (Sender Policy Framework) records that authenticate the sender’s IP against potential spoofing. If anything looks suspicious (for example, the email claims to be from a known contact but the IP location is in a different country), this could be a sign of a phishing attempt or spam.
Remember, each email header analyzer tool might have a slightly different process, so always refer to the specific instructions for the tool you are using.
Deep Dive into Email Headers: Analyzing Key Elements
As we’ve seen, an email header contains links to several pieces of crucial data. Let’s delve deeper into some of the most essential elements and their role in email header analysis.
IP Addresses and the Art of Tracing Emails
The ‘Received’ lines in an email header reveal the IP addresses involved in the transmission of the mail, the path it took from the sender to the recipient, and the date and time of each hop. As such, these lines are a treasure trove for tracing an email’s journey.
In an email header, every ‘Received’ line corresponds to a server that the email passed through. The topmost line is the last server the email touched, while the bottommost one is the server where the journey began. Each line will typically contain the IP address of the server and the exact time the message was received.
With the help of an IP address, you can determine the sender’s approximate location. However, remember to note that a skilled attacker can forge these lines, so they should not be the sole criterion for determining an email’s legitimacy.
Understanding Sender Policies: Received-SPF
SPF, or Sender Policy Framework, is an email domain authentication method designed to prevent spammers from sending emails on behalf of your domain. The ‘Received-SPF’ line in an email header indicates the SPF check results.
If the SPF check fails, it’s an indication that the email might not be from the sender it purports to be. This could be a sign of a phishing attempt or spam. An email header analyzer tool can identify these issues, flagging them for your attention.
Deciphering the Message-ID
The ‘Message-ID’ is a unique string of characters assigned to each message when it’s first created. Think of it as a digital fingerprint for every email.
While the primary purpose of the ‘Message-ID’ is to ensure that each email is unique, it can also be used to trace an email or group related emails together. If the ‘Message-ID’ is missing or is present in multiple emails, it might be a sign of spam.
Return Path and Reply-To: Understanding the Difference
The ‘Return-Path’ and ‘Reply-To’ lines in an email header can sometimes be confusing. The ‘Return-Path’ in mail header is the email address to which bounce-backs are sent if the email can’t be delivered to the recipient. It’s crucial for email marketers as keeping a clean return path can help prevent being marked as spam.
On the other hand, ‘Reply-To’ is the email address that will be auto-filled when the recipient clicks ‘Reply’ in their email client. If the ‘Reply-To’ address differs from the ‘From’ address, the recipient’s reply will be sent to a different email address than the original sender’s.
The Role of Email Headers in Cold Email Outreach
Cold email outreach is all about delivering the same content type the right message to the right person at the right time. And email headers play a vital role in this process.
Firstly, the headers ensure that your email reaches its destination. They carry essential routing information that guides your email on its journey from your outbox to its destination in your recipient’s inbox.
Secondly, analyzing your email headers can help identify delivery issues. For instance, if you notice that your emails are not reaching their intended recipients or are being marked as spam, your email headers might offer clues to the problem. You might find that your email server’s IP address has been blacklisted or that there’s a problem with your SPF settings.
Finally, email headers are critical for tracking email opens and clicks, key metrics for gaiving insight into the effectiveness of your cold email campaigns.
Harness the power of email header analysis tools to improve your cold email outreach. One of the best ways to do this is by using an email header analyzer tool. Sign up for Mailarrow, our cold email outreach software, and discover the power of data-driven email marketing today.
