So I recently got an email from someone on Craigslist, and needed to find out a little more about them. The email address gave me no information about who they were, where they lived, or who they worked for. I googled the address, but nothing valid came up. So I had to find a decent email address lookup tool.
I found this email lookup tool, and I recommend it. Though it comes with a per-use cost, it's worth it, as the interface is very simple, and the results are pretty comprehensive.
It also offers the functionality to find a person's email address by their name, but this currently only works in the US.
So what are you waiting for? Find out whose email address that is now!
