What is Email Analysis?

Email analysis is the process of examining an email to determine whether it is safe, suspicious or malicious. This includes checking:

• Sender information
• Links
• Attachments
• Email headers
• Writing style

In simple terms, you investigate an email before trusting it.

Why is Email Analysis Important?

Cybercriminals rely heavily on email attacks because they target people directly. Email analysis helps:

• Detect phishing attempts
• Identify fake senders
• Prevent malware infections
• Protect sensitive information

Why Attackers Use Email:

Email attacks are effective because:

• People trust familiar brands
• Emails can create urgency
• Users may click without thinking

Even experienced users can be fooled.

Common Types of Malicious Emails

Before analyzing emails, you should understand some of the common malicious emails.

1. Phishing Emails:

These email are designed to steal:

• Passwords
• Banking details
• Personal information

Usually pretend to be:

• Banks
• Companies
• Online services

2. Malware Emails:

Contain:

• Malicious attachments
• Dangerous download links

Goal:

• Infect systems

3. Spoofed Emails:

The sender address is faked to appear legitimate.

4. Scam Emails:

Try to trick victims into:

• Sending money
• Sharing sensitive information

Step-by-Step Email Analysis Process

Let’s go through a simple beginner workflow of analysing emails.

Step 1: Check the Sender Address:

This is the first thing you should inspect. Attackers often use:

• Misspelled domains
• Fake addresses

Example:

Real:

• support@company.com

Fake:

• support@cornpany.com

Notice the subtle difference?

Step 2: Analyze the Subject Line:

Suspicious emails often create:

• Fear
• Urgency
• Curiosity

Examples:

• “Your account will be suspended!”
• “Urgent payment required!”

Attackers want you to react quickly.

Step 3: Look For Suspicious Links:

Never trust links inside an email immediately. Hover over links and check:

• Destination domain
• Strange URLs

Red Flags:

• Random characters
• Shortened URLs
• Misspelled domains

Step 4: Inspect Attachments:

Attachments can contain malware. Be cautious with:

• ZIP files
• EXE files
• Office documents with macros

If unexpected, don’t open them.

Step 5: Check the Writing Style:

Many phishing emails contain:

• Grammar mistakes
• Unusual wording
• Generic greetings

Examples:

• “Dear user”
• “Dear customer”

Legitimate companies usually personalize emails.

Step 6: Analyze Email Headers:

Headers contain technical information about the email. They can reveal:

• Sending servers
• Email path
• Authentication results

Why Headers Matter:

Headers help identify:

• Fake senders
• Spoofing attempts

Beginners don’t need to master headers immediatel but learning basics helps a lot. Let’s show you a simple example of header analysis of a real-world email received on Gmail. Go to your Inbox and open a mail. Go to the vertical dots (move button) at the top right of the email and click on it as shown below.

Click on “Show original”.

This should show you the entire email headers of the particular mail.

Let’s learn about each header in detail.

Delivered To:

Email address to whom the mail has been delivered.

Received:

This header indicates all the SMTP servers through which this email has passed through before reaching to your Inbox. This contains server IP address, SMTPID etc.

X-Google-SMTP-source:

It shows the transferring email using a Gmail SMTP server. If this header is present, then it usually means this was transferred by GMAIL SMTP server.

X_Received-BY:

This header indicates the last visited SMTP server the mail reached before reaching your Inbox. It contains Server IP address, SMTP ID of the visited server and Date & time when the email was received by the SMTP server.

ARC-Seal, ARC-Message-Signature, ARC-Authentication-Results: ARC stands for Authenticated Receiver Chain (ARC). This is used to preserve email authentication results and to verify the identity of email intermediaries that forward a manage to its final destination (i.e. your Inbox).

SMTP-mailfrom:

You can see the IP address of the sender of the email.

Return-Path:

This is the path specified to go when email is bounced or not sent.

Received SPF:

SPF stands for Sender Policy Framework. This is used to prevent sender address forgery. It SPF is set to PASS, the Email source is valid, if it is softfail, it is likely the email source is fake and if it is having value Fail, source is invalid.

This is how Email headers can be analysed.

Step 7: Verify Before Taking Action:

If an email seems suspicious, don’t click immediately. Instead:

• Visit the official website manually
• Contact the company directly

Real-World Example (Simple Scenario)

Imagine receiving an email saying:

“Your account has been locked. Click here immediately.”

You notice:

• The sender domain looks slightly different
• The link points to another website
• The email creates panic

These are classic phishing indicators.

Tools Used in Email Analysis

Beginners can use simple tools to help analyze emails. Common Tool Types:

• Header analyzers
• URL scanners
• Attachment scanners

These tools help identify suspicious indicators.

Common Mistakes Beginner Make

Avoid making these mistakes.

Trusting Display Names:

Attackers can fake names easily. Always inspect actual email address.

Clicking Too Quickly:

Urgency is a common attacker tactic.

Ignoring Small Details:

Tiny spelling changes matter.

Assuming “Professional Looking” Means Safe:

Some phishing emails look very convincing.

Tips to Improve Your Email Analysis Skills

Slow Down:

Most mistakes happen because users rush.

Think Like an Atatcker:

Ask:

• How is this trying to manipulate me?

Practice Regularly:

Analyze:

• Spam emails
