Find someone by their Gmail, Yahoo or Outlook address

Last updated: January 27, 2023

You have probably received an email from a sender you don't know. Maybe they claim to know you, but their email address doesn't tell you anything.

In any case, you want to know who is hiding behind this email address in order to know how to respond better. In this article, we will show how to trace an email address back to its owner.

Why trace an e-mail address?

First of all, why bother to trace the IP address of the email?

These days, malicious emails are all too common. Scams, spam, malware and phishing emails are commonplace in the inbox. Finding the source of this email will give you a chance to find out who and where the email came from.

In other cases, you can trace the origin of an email to block a persistent source of spam or abusive content, allowing you to free your inbox of these.

How to trace an e-mail address?

Did you know that each email contains a lot more information than what appears in most email clients? There is a wealth of sender information included in the email header, information that you can use to trace the email back to the source.

You just need to know where to look, as well as what you're looking at.

To open the email header and find the sender of the message on different email providers, follow these steps below:

On Gmail

1. Open your Gmail account.
2. Select the email you want to track.
3. Then, in the upper right corner of the email, click on the three dots to open a drop-down menu.
4. Click on Show original to open the email header.

On Yahoo

1. Open your Yahoo Mail account?
2. Open the email message you want to inspect.
3. Above the message pane, click the icon Plus.
4. Select Show raw message. This opens a new tab where you can see the email header.

On Outlook

1. Open your Outlook email account.
2. Double-click the email message you want to view.
3. Go to File>Properties.
4. You will find what you are looking for in Internet headers.

On Apple Mail

1. Open your Apple Mail account.
2. Select and open the email message you want to trace back to its owner.
3. Then go to View > Message > Raw Source to open the email header.

Understanding Email Header Data

Before we dive into the email header to learn how to trace an email address back to its owner, we need to understand what data it contains.

• To: this is the sender of the email. However, do not rely on this as this information can be faked by spammers.
• Reserve : Displays the exact date the email was sent.
• Reply-To: this is the email address to which you send the reply.
• Subject: Obviously the subject of the email.
• Return-Path : This is an essential element that provides the email address to which the system will send its message. This is where unsent or bounced messages end up.
• Received: the "Received" line lists each server the email passes through before reaching your inbox.
• MIME-Version: MIME stands for Multipurpose Internet Mail Extensions and represents the email format standard currently in use.
• Content type: lets the email client or browser know how to "read" the content of the email. It will probably be either UTF-8 and ISO-8859-1 character set.
• SignaturesDomainKeys and DKIM : By associating the domain name with the email, DomainKeys and DKIM (DomainKeys Identified Mail) signatures help email services recognize and authenticate messages.
• ARC-Authentication-Results: : ARC identifies email forwarders. It stands for Authenticated Receive Chain.
• ARC-Message-Signature: validates email header information, much like DKIM does.
• ARC Seal: Verifies the content of the authentication results and the message signature.
• SPF received: The SPF or Sender Policy Framework is a part of email authentication which prevents forgery of sender address of emails.
• X Google SMTP Source: indicates if the email used the Gmail SMTP server to forward.

Info: you don't need to understand what all these words mean to trace an email. But if you learn how to scan through the email header, you can quickly track down the sender of the email.

Find the original sender of an email

To trace the IP address of the sender of the original email , go to the second Received in the email header. Next to the first Received line is the IP address of the server that sent the email. Sometimes it appears like X-Originating-IP ou Original-IP.

Find the IP address, then head to MX-Toolbox . Enter the IP address in the box, change the search type to reverse lookup using the drop-down menu, then press Enter.

The search results will display a variety of information related to the sending server.

3 free tools to track emails and IP addresses

Of course, there are tools that automate this process for you. It is convenient to know more about email headers easily, but sometimes you get wrong information.

Check out the following header parsers:

• G Suite toolkit message header.
• MX Toolbox Email Header Analyzer.
• IP Address Email Header Trace (email header analyzer + IP address tracer).

However, the results do not always match.

Your success with tracing an email will vary depending on the sender's email provider. For example, if you try to locate an email sent from a Gmail account, you will only discover the location of the last Google server that processed your email, not the original sender's IP address. .
