If person use any desktop client(like outlook,Evolution mail etc) to send email then you can trace his I.P. From email. But if he send from browser then you get location of his email provider.
Open the header of the email message and look for lines that say “Received: from” followed by an IP address in square brackets. If there are multiple entries, use the IP address mentioned in the last entry.
Now paste the IP address in this trace route tool and you should get a fairly good idea about the location of the email sender.
you should also try a people search service like Pipl and Spokeo –both services let you perform reverse email lookups but Spokeo has a more comprehensive database than Pipl.
