For the everyday user, it can seem as though a disproportionately large part of the day is spent on spam filtering. Just about everyone is familiar with the "performance-enhancement" and refinancing ads that clutter inboxes and make it nearly impossible to conduct legitimate business. Most often, folks in this situation simply "clear out" their mailboxes by going message to message and deleting the junk.

It'd be a whole lot easier, however, if these same people could just block unwanted email messages in the first place. It is this very principle that has led to a boom in spam filtering products on the marketplace. Some of these do their prescribed purpose and yank unwanted messages. Others are far more advanced and can be customized to do any number of spam filtering operations to make life a lot easier for you.

Customized Spam Filtering

Whereas generic spam filtering software makes its best guess as to what you'd deem junk and what you wouldn't, customizable spam filtering lets you say with assuredness. Choose to block incoming messages from a known spam domain or just an individual troublemaker whose email address you know. You can also stop incoming messages by filtering out certain subject lines. That way you can guard against repeat offenders who frequently change their own email accounts in the hope of thwarting filtration devices.

More advanced spam filtering includes screening out keywords and keyphrases such as "for sale" or "buy now." A word of caution, however, is in order here. You must be careful when choosing such phrases for screening. After all, your employer might send messages with news of a "limited-time" deal or "special" news and would probably frown on having these missives sent to your recycling bin.
