Receiving suspicious mail can be unsettling.
That message that arrives with a striking issue or that promises unbelievable inheritances may conceal an attempt to phishing or a carefully prepared fraud.
The truth is that, even if criminals try to disguise themselves, they always leave behind some digital trail.
And you can learn how to decipher it.
📩 Why is it important to trace the origin of an email in Gmail?
Cybercriminals are perfecting their methods every day.
It is no longer enough to detect spelling errors or poorly designed logos.
Nowadays, many fraudulent emails look totally legitimate.
The only way to be sure is to check the hidden technical information that travels along with the mail, something that Gmail allows you to do easily.
In addition, learning to analyze headers is like getting digital superpowers: you will be able to know if an email really comes from Google, your bank or a trusted company.
🕵️ The hidden trick in Gmail: show the original
Gmail not only saves the visible content of the email.
Each message includes a metadata package which details the path it took from when it left the origin server until it landed in your inbox.
To see them:
- Open the suspicious mail.
- Click on the three-dot menu (top right).
- Select "Show original".
A new tab will open with the full content of the message, including headers, IP addresses and authentication results.
🌐 How to read email headers
The headers are the "DNI" of the e-mail.
There you can find several key fields:
- From → indicates who sent the message, but it may be forged.
- Return-Path → shows the actual response direction.
- Received → points out which servers the mail went through and which one was the first to send it.
- Authentication-Results → shows whether the message passed security tests (SPF, DKIM, DMARC).
📌 Practical example:
An email may appear to come from "soporte@paypal.com"but in the field Return-Path appears "contacto@fraudulent-site.ru".
This is already a clear sign of a scam.
🖥️ Locate the source IP address
The IP is one of the most revealing data.
The "Received: from" header usually contains a number such as:
Received: from mail.example.com (203.0.113.45)
That 203.0.113.45 is the IP address.
If you copy that value and look it up in IPLocation o WhatIsMyIPIf you have a valid email address, you will know the approximate location of the server from which the email was sent.
👉 Keep in mind: the IP will not give you the exact address of a person, but it will tell you if the message really went out from your country, or from a remote server in another part of the world.
🚨 Signs that give away a suspicious mailing
Beyond the technical side, you can also look at very obvious clues:
- The mailing address does not match the official sender.
Example: "seguridad@banco.com" vs. "seguridad@banco.seguro123.com". - Links do not point to the original site.
Hover your mouse over it and you will see the actual URL. - Odd spelling or grammatical errors.
Many frauds are automatically translated. - Excessive urgency or threats.
Phrases like "verify now or you will lose your account" are common in scams.
🔒 External tools for interpreting headers.
If reading a block of headers seems complicated, there are pages that do it for you.
Simply copy and paste the "Show original" information:
These tools show you the mail path in a clear and easy-to-understand graph.

❓ Frequently asked questions about the origin of mails in Gmail.
Is it always possible to find the IP of the sender?
Not always. Some services mask the IP for privacy, especially if the sender uses providers such as Gmail, Outlook or Yahoo.
Can an email pass verification and be a fake?
It is rare, but possible. The most advanced attackers try to configure their domains with valid SPF and DKIM. That is why it is also a good idea to verify the content of the message.
Is it legal to trace the IP address of an email?
Yes, as long as you only use the information included in public mail and tools. It would be illegal to use such information for harassment or fraud purposes.
Can I report a suspicious email?
Yes, Gmail has the option to "Report phishing". In addition, if the email impersonates your bank or company, you can forward it to the corresponding security area.

⚠️ Actual example of a scam
A user receives an email that appears to be from Amazonwith the subject "Problem with your order".
The message includes a link to "verify your data".
When you open the "Show original", you will discover that the Return-Path en "soporte@amz-client-check.cn"and the IP points to a server in China.
It clearly does not come from Amazon.
With this technique, the user avoids giving his credentials and realizes that it was a scam.
✅ Conclusion: the truth is in the details.
In a digital world full of traps, technical information is your best ally.
Knowing where a Gmail email comes from is a skill that anyone can learn with a little practice.
