If you work with email on a daily basis, using a spam filter to quickly sort through irrelevant messages is a smart move. However, it’s important to have a basic understanding of how spam filters work. If you’re not using your spam filters properly, you may find yourself either flooded with junk or constantly searching for misplaced messages.

Language spam filters are an easy type of spam filter to use, since they merely discard all emails not written in your native language. The Internet is a global marketplace, so spammers come from around the world. However, with language spam filters, you don’t have to be bothered by annoying sales pitches in a language you can’t read!

Content spam filters use sophisticated programming rules to determine whether or not an email is likely to be spam based on the text of the message and other relevant characteristics. This approach is quite effective at minimizing spam, but it does occasionally result in the misdirection of requested email newsletters and other similar bulk messages. If you’re using content spam filters, you’ll want to check your spam folder on a regular basis to make sure no errors have been made.

Header spam filters are similar to content spam filters, but they attempt to see if the header information on an email message appears to have been forged. Although email with a forged header is almost certainly spam, not all spam messages have forged headers. Therefore, header spam filters are best used in conjunction with other email management tools.

User spam filters can be effective spam filters, but they require a significant time investment to use properly. You’ll need to make a point of examining all spam emails you receive and setting up a series of rules for your email client to use in order to filter all incoming messages. For example, you could have all emails from your friends and work associates delivered to one inbox, all email newsletters you’ve requested sent to a second box, and all other messages delivered to third spam box.

If you find yourself completely overwhelmed with the amount of spam you receive on a daily basis, permission spam filters may be the solution you’ve been searching for. This type of spam filter blocks all email that does not come from an approved source. If you’re using permission spam filters and someone sends you a message for the first time, he/she will receive an automatic reply requesting the completion of validation form. If the sender fails to complete this form, the message is blocked. Completing the form is a one-time process, but you should be aware that many people find this extra step to be a nuisance in their correspondence.
