The two reverse email address lookup services that we review contain a useful feature for checking whether the sender of an email that you received is a spammer. That is, a person, group, or organization that sends you unwanted and undesirable (and sometiomes illegal) email messages. These messages:

1. Stuff your inbox with information about products and services that you do not want and have not previously expressed interest in.

2. Entice and trick you to purchase products online with your credit card to take your money without sending you the products, and to steal your credit card purchase information.

3. Infect your computer with viruses and worms that degrade and ruin the operation of your computer, spy on your online activities, steal your private personal and business data, or use your computer as a base for illegal activities that target others on the internet.

4. Fool you into intentionally revealing personal information such as passwords and your social security number.

5. Send you or your family members pornographic images for nefarious purposes.

All this (and more) can occur when you click to open an email message from a spammer. You can defend yourself against these attacks by doing a reverse email address lookup using my recommended website-based services to determine whether the email address from which the message was sent is found in a blocklist (a.k.a., blacklist).

These blocklists contain Internet Protocol (IP) addresses – unique numerical identifiers assigned to each and every computer on the internet – from which SPAM messages have been known to be sent, as well as websites that are otherwise involved in facilitating spamming.

The reverse email address lookup service checks that the IP address of the suspect email message sent to you is on a blocklist (actually, they check multiple blocklists, more than two dozen). If the email address is found on the blocklist then it is best that you delete the email and that you do not open it.

Without the reverse email address lookup services you will need to find and gain access to the blocklists yourself and search them manually. There are many different blocklists to choose from. They have different requirements for flagging an email and for getting on the blocklist, as well as for remaining on it (some having more strict criteria than others). Some employ very sophisticated and advanced methods involving pattern recognition and statistical analysis. Keeping the blocklist current is a challenge that requires much effort and constant attention, as new spam emails show up every day and spammers are constantly changing and improving their methods and tactics. It is much easier to have an expert program search for you automatically and quickly across many blocklists, just with the push of a button.

The reverse email address services that are reviewed here quickly determine whether an email address is on one or more of the top blocklists.

Besides the many benefits of accessing a reverse email address lookup service for locating a person’s name from their email address or finding an email address from a person’s name, the reverse email address lookup services reviewed allow you to check whether the sender of an email message you received has been blocklisted. This adds a layer of safety to your online activities by helping to prevent you from becoming another victim of a spammer’s unethical and illegal exploits. Today, the capability to perform a reverse email address lookup on demand, routinely, and without delay, is an indispensable necessity and convenience for use during our ever-increasing time spent online.
