A simple email address can reveal much more information than you might think. Using an email address in a free reverse email Web search can actually turn up all sorts of personal identifiers, including name, phone number, address, and a variety of public records. It all depends on where that particular email address has been posted publicly on the Web.
Start with search engines
Type the email address into your favorite search engine and hit "enter". If that email address has been placed publicly on the Web; on a blog, on a personal Web site, on a message board, in a social networking community, etc. - then it should turn up in a simple Web search.
In order for this reverse email search to be as effective as possible, it's suggested to use at least three different search engines (for a comprehensive list of over 100 search engines, read The Ultimate Search Engine List).
Use specialized social networking search utilities
Not all social networking sites will show up in a general search engine query. That's when it's time to turn to specialized social networking search tools, such as YoName, Zabasearch, Zoominfo, These sites search across a variety of social networking communities; if the email address you're looking for has been put up on one of these sites, chances are, you'll find it using these social search tools.
People search sites
There are many impressive Web search tools online that focus specifically on finding people; here are fifteen people search engines that search across social networking services, search engines, databases, etc. to find tidbits you might not usually find on a rudimentary search. Type in your email address to one of these people-specific search engines and if it's been publicly shared, it's going to show up in the search results.
Invisible Web email search
Using the Deep, or Invisible, Web (the vast part of the Web that doesn't necessarily show up in a rudimentary Web search) to find information related to an email address can reap some impressive results. These Invisible Web people search engines and sites can help you access more of the Web that you might not have otherwise been able to.

If the email address you're tracking has not been posted publicly, then naturally it follows that this email address will not be found on the Web. However, all is not lost; use the following people search resources to find what you're looking for online:
