People can run free reverse email lookups on websites such as Pipl, Intelius and EmailSherlock by putting the email address into the search bar and hitting enter. The type of results revealed varies, but a search will bring up social media profiles, websites, blogs and other related webpages.
Running a reverse email search only brings up results for public profiles that were set up with the email address in question. Often, personal information, such as a name or address, will not show up, or users might have to pay extra for it.
Not all supposed free reverse email lookup websites are truly free. Many only give limited information unless customers purchase additional information or sign up for a subscription.
