There are different reasons why you may want to be able to trace an email to its source IP, one likely reason being that you want to find out the origin of that those annoying emails that consistently dodge your spam filter, or you want to confirm the origin of an email requesting for sensitive information. You can accomplish this task using its IP address.

Not sure what an IP address is? Think of it as a street number in a geographic directory. It is a unique number automatically given to devices connected on a network and with it, devices communicate with other devices and servers both within and outside the network.

IP addresses can be used to pinpoint the origin or destination of network traffic and this is the address that we will check for in the header of the email whose location you want to decipher.

What is an Email Header?

All emails come with a lot of data especially about their sender and destination but a lot of that information is collapsed by default. You must be familiar with the 'To', 'From', and 'Subject' fields – these and other fields belong in the so-called email header section and you can easily access them in just about 3 steps that depend on your email client app.

Locating the IP Address

When you choose to view the email in its raw form you’ll be welcomed with texts that seem like jargon. They’re not. Quickly find the sender’s IP address by pressing Ctrl + F and then searching for “Received” or “Received from“. Found it yet? That’s the sender’s IP address right next to it.

Possible Drawback

While there is a good chance of this method working on any email, it can fault when you trace the IP address of emails sent form GMail and you’re lead to the location of Google’s servers instead of the actual sender. This may be a good or bad thing depending on which side of the fence you’re standing on.
