It can be used to find out who people are in carbon copy (CC) lists, it can be used with spam that gets into an inbox and it can be used find out the family names of emails signed by someone only using their first name.Finding out who sent an email can be of great advantage; it can stop people from accidentally deleting emails they thought were spam but may be from a long lost friend. When people receive emails from an unknown sender the instant reaction is often just to assume it is junk mail trying to sell something, when really it may be an important email from someone who has not been spoken too in a while.Looking up email addresses to find out where they came from allows you to see the origin of an email. Often information such as I. P address, company name and location are available from the sites used to search. The information contained on these sites comes from sources such as public records and phone directories.Viruses are often received via email from unknown senders; these can harm your computer as well as send themselves to everyone stored in your contact list. Scams are also widely sent this way and can cause no end of problems. By searching for the sender email it allows people to see whether an email is harmful or legitimate.Web mail providers such as hotmail do not keep directories of emails to protect the privacy of their customers. In the early days of the internet emails were kept in this way to make finding people easier, as they wanted to be found. Often the only way to find people in the modern internet era is by using a reverse look up.All that a person needs to do to be able to find out information about someone is simply type the email address into a search bar and within a few moments the results are shown. Many sites are free to use but may not necessarily show all the required information. Sites that charge a fee are generally more accurate and show a lot more information.As email has become more widely used in the modern society as a way of communicating it becomes very helpful to be able to find information from just an email address. As phone books were used in the past so a hotmail reverse email lookup can be used today to find out information about people.
