Email Header Analyzer

To find this, open your email, click the menu options, and select "Show Original" (Gmail) or "View Message Source" (Outlook).

This analysis is done completely inside your browser. We never upload your sensitive email data to our servers.

Detailed Example

See how the Ease Tools Email Header Analyzer helps you catch phishing scams.

Problem: You get an urgent email that looks like it's from "PayPal Support," asking you to log in and verify your account. The name looks real, but you want to be sure it's safe.

Solution: You open the email settings, copy the raw header code, and paste it into our analyzer to check the math behind the message.

Step 1: The tool finds the true "Return-Path", showing the email actually came from [email protected].
Step 2: It reads the Authentication-Results line in the code.
Step 3: SPF shows FAIL because the sending IP address doesn't belong to PayPal.
Step 4: DMARC shows FAIL, proving the email is a dangerous fake.

Result: The red FAIL badges clearly warn you that this is a scam, saving you from a potential cyber attack.

How It Works

Read email headers and trace routes in a few simple steps:

Step 1: Find the Header
Email apps hide the messy routing code. In Gmail, click the 3-dots on the right and choose "Show Original". In Outlook, go to File > Properties to find "Internet Headers".
Step 2: Paste the Code
Copy that big block of technical text and paste it straight into the main box of our analyzer.
Step 3: Text Matching
Our tool uses smart text matching (Regular Expressions) to quickly scan through hundreds of lines and find the important details.
Step 4: Security Check
It pulls out the exact pass or fail status for SPF, DKIM, and DMARC protocols, which tell you if the sender is verified.
Step 5: Read the Report
Look at the clean table output. You will clearly see the real sender, the true originating IP address, and easy-to-read security flags.
Step 6: Save Your Data
Use the copy button or download the report as a text file if you need to send it to your IT team for a security review.

Understanding Email Security

Learn the basics of email routing, signatures, and server checks.

What is an Email Header?
It's a block of hidden code attached to every email. Think of it like a digital shipping label that shows every stop the message made before reaching you.
Why Check Headers?
Scammers can easily fake the "From" name you see on your screen. Analyzing the header shows you the actual server the email came from.
What is SPF?
Sender Policy Framework. This is a rule that lists exactly which IP addresses are allowed to send emails for a specific company.
What is DKIM?
DomainKeys Identified Mail. This adds a digital signature to the email. If a hacker alters the email on its way to you, this signature will break and fail.
What is DMARC?
It brings SPF and DKIM together. If an email fails those checks, DMARC tells your email provider whether to delete the message or send it to spam.
The "Received" Lines
Every time an email jumps between servers, a new "Received" line is added. Reading these lines helps trace the physical route of the message.
The "Return-Path"
This is the real, hidden email address where bounced messages go. If an email looks like it's from Apple, but the return path says something weird, it's a scam.
The "Message-ID"
A unique tracking number created by the server that sent the email. It helps IT admins track specific messages across networks.
Email Spoofing
A trick where hackers change the header details so the email looks like it came from someone you trust, like your boss or your bank.
Catching Phishing
If the sender claims to be Netflix, but the tool shows the originating IP is from a random server overseas, you've just caught a phishing attempt.
What is an MTA?
A Mail Transfer Agent. It's the software on a server that actually handles the routing and delivery of your emails across the internet.
The SMTP Protocol
Simple Mail Transfer Protocol. These are the core rules that tell different email programs and servers how to talk to each other.
IP Blacklists
Once you find the sender's real IP address from the header, you can check if that server is on a public blacklist for sending spam.
User-Agent / X-Mailer
This line in the header tells you what app the sender used to write the email, like Outlook, Apple Mail, or an automated marketing script.
100% Private Analysis
We don't use external APIs to read your emails. Everything happens right inside your own browser so your private data stays safe.
Free to Use
The Ease Tools Email Header Analyzer is totally free for anyone who wants to check if their emails are safe and secure.

Key Features

Everything you need to verify an email's origin:

Smart Code Reading
The tool quickly sorts through all the messy, complicated text in a header to pull out the exact details you need to see.
Clear Security Status
We take the complicated authentication results and turn them into simple, color-coded PASS or FAIL indicators for SPF, DKIM, and DMARC.
Find the Real IP
The tool reads through the server stamps to locate the very first IP address that originally sent the message into the network.
Expose the True Sender
It pulls the hidden Return-Path address out into the open, letting you easily see if someone is trying to trick you with a fake name.
Clean Table Layout
Instead of giving you a wall of text, your results are presented in a neat, organized table that is very easy to read.
Works Without Servers
Because this tool works directly in your browser without sending data to an API, it runs incredibly fast and protects your privacy.
Mobile Friendly
The entire tool, including the clean results table, looks and works great on smaller phone screens.
Easy Exporting
Grab your parsed report with one click of the copy button, or save it as a text file for your records.

Frequently Asked Questions

Common questions about email security and headers:

What is an email header?
An email header is a hidden block of text attached to every email message. It includes vital details like the sender's IP address, the servers the email traveled through, timestamps, and security authentication records.
How do I find the email header to paste here?
In Gmail, open the email, click the three-dots menu, and select "Show original". In Outlook, open the message, go to File > Properties, and look at the "Internet headers" box at the bottom. Copy all of that text. Read the Google Workspace Guide for more help.
What is SPF, DKIM, and DMARC?
These are rules that prove an email is real. SPF checks if the sending server is allowed. DKIM acts as a digital signature. DMARC tells the receiving server what to do if the email fails these checks. Learn more about the DMARC protocol on Wikipedia.
Can this analyzer tell me if an email is a scam?
Yes! If an email claims to be from your bank, but the Return-Path is different, or if the SPF/DMARC status shows FAIL, the email is highly likely to be a spoofed scam. Always be cautious.
