Spam Information

What is Spam?

Spam is the term used for any unsolicited email. A better description of spam is email that is unsolicited and does not have a legitimate return address label. There are email messages that you receive that are still unsolicited; however, they are coming from legitimate sources.

How did I get on their lists?

There are many ways your email address could have been submitted to a list. First, you may have subscribed to an email distribution list or filled out an online form for a company that does not have a privacy policy. The distribution list owner most likely sold the list to an email distributor.

Another method is by specialized software that hunts for email addresses. The software is set loose on web sites, bulletin boards, Usenet, and other documents published on the internet. These address hunters, create their lists, and use them for email distributors.

Finally, there's the sneaky way... The spammers send a message to some list that they have. However, that list may have lots of invalid addresses. So, they clean it up by putting a link on the bottom of a message telling you to "click here" to remove yourself from the list. Once you click here, the spammer now knows that this was a valid address, and moves your email address to a "good" list.

What do I do now?

This is a difficult question to answer. The answer is "it depends." If it is true spam, there may not be an easy way to get your address off their lists. However, if it is unsolicited email from a legitimate company, you can compose a new message (don't reply) to the company that is "advertised". Ask them to remove your email address from their list. Many times legitimate companies have a generic address such as abuse@company.com, or postmaster@company.com.

With true spam, the return address is usually invalid. Therefore, it is difficult to determine who really sent it. Many times you'll see spam from Gmail.com or Yahoo.com. These are just about impossible to trace without a lot of technical research to trace the message. These messages probably traversed many networks or even countries before it ended up in your Inbox.

How do I avoid getting on lists?

This is another tough question. Make sure that you verify any web site's privacy policy before submitting your email address or name to the site. This includes online purchases and subscriptions. If you do receive unsolicited email, don't reply to the message or click on the "unsubscribe" option, unless you know it's a valid option.
