Privacy: the file is processed and deleted immediately after parsing. Temporary storage is blocked from public access.
Note: SPF/DKIM/DMARC results shown are read from the email’s own headers (e.g. “Authentication-Results”). This indicates what a receiving server already decided for that message.

IMPORTANT NOTE:
For the safety of our servers and your personal privacy, uploaded emails are not stored. They are analysed temporarily and all data is deleted immediately after processing. This protects both you and us, as many uploaded emails may contain security issues or potential malware.

THE EMAIL CHECKER SYSTEM:
The email checker system never executes the email, accepts .eml or .msg. Reads it as plain text and extracts headers (From, SPF, DKIM, etc.) and then deletes the file.

It does not open attachments, execute scripts, render HTML, run macros or load external content.

How to use the email verification tool

You can upload an email file directly into the form.

Option 1 — Drag and drop

  1. Drag the email file into the upload area.
  2. Click analyse.

Option 2 — Browse your computer

  1. Click “Browse”.
  2. Select the email file.
  3. Click analyse.

Important note for Outlook users

If you drag an email directly from Outlook into the form, you may see:

“No file selected.”

This happens because Outlook uses a virtual file system that some browsers cannot read correctly.

How to fix it

  1. Drag the email from Outlook into a folder on your computer.
  2. We recommend using your Downloads folder.
  3. Once saved, drag the file from that folder into the website form.

This ensures the email is uploaded correctly for analysis.

Email Verification Tool

Check email authenticity, security, and deliverability in seconds

Email is still the most common way businesses communicate. But it is also one of the biggest attack surfaces for phishing, spoofing, and fraud.
Our Email Verification Tool allows you to upload an email file and instantly analyse its technical headers, authentication results, and security signals.

Whether you’re an IT professional, business owner, or everyday user, this tool helps you understand:

  • Where an email really came from
  • Whether it has been tampered with
  • If it passed key security checks
  • Why it may have landed in spam

What the Email Checker Tool Does

Our tool analyses the hidden technical data inside an email to provide a clear, easy-to-understand report.

Every email contains a header — a block of metadata that records:

  • Sending servers
  • Routing path
  • Authentication results
  • Timestamps
  • Security checks

These headers help determine whether a message is genuine or malicious.

The tool decodes this information and presents it in a readable format, including:

  • Sender verification
  • Server path
  • Authentication results
  • Spam and security indicators
  • Technical diagnostics

 

Why email verification is important

Email threats such as phishing, spoofing, and impersonation are increasing every year. Attackers often send emails that look genuine but come from unauthorised sources.

Modern email security relies on three main authentication methods:

SPF (Sender Policy Framework)

Confirms that the sending server is authorised to send email on behalf of a domain.

DKIM (DomainKeys Identified Mail)

Adds a cryptographic signature to verify that the email hasn’t been altered during transit.

DMARC (Domain-based Message Authentication, Reporting & Conformance)

Combines SPF and DKIM to tell receiving servers how to handle unauthenticated messages.

Together, these protocols help prevent spammers and attackers from sending emails using domains they don’t own.

If any of these checks fail:

  • Emails may go to spam
  • Messages may be rejected
  • Your domain could be used for phishing
  • Customer trust can be damaged

Common email problems this tool helps diagnose

Emails going to spam

Often caused by:

  • Missing SPF, DKIM, or DMARC
  • Incorrect DNS configuration
  • Poor sender reputation

Spoofed or phishing emails

Attackers frequently impersonate trusted domains to trick users.

Header analysis can reveal:

  • Fake sender addresses
  • Suspicious routing
  • Failed authentication checks

Deliverability issues

Even legitimate emails can fail due to:

  • Misconfigured authentication
  • Forwarding issues
  • Broken DKIM signatures
  • Incorrect SPF records

What information the report shows

After uploading your email, the tool will display:

Authentication results

  • SPF: Pass or fail
  • DKIM: Pass or fail
  • DMARC: Pass or fail

Successful authentication is usually indicated by results such as:

  • spf=pass
  • dkim=pass
  • dmarc=pass

Email route

A breakdown of the servers the email passed through.

Sender details

  • Actual sending domain
  • Source IP address
  • Mail server identity

Security indicators

  • Spam verdicts
  • Policy results
  • Possible red flags
