The impact of spam on Internet uses varies, but nobody escapes untouched, that’s for sure, so there is the demand for spam blocker. An active Internet surfer or a business, such as freelance or dropship, that works online a lot, receives hundreds if not thousands of messages that are hard to separate into legitimate mails and spam. Software companies have come up with a solution in the form of free and paid spam blockers.
Depending on the operation model, anti-spam tools fall into three distinct categories. A first group of spam blockers is that of the plug-ins. Such programs are installed on the PC and take care of the downloading the messages and eliminating the unwanted emails. For some users this may not be the ideal anti-spam option.
Spam blockers are also available as stand-alone applications. Constantly communicating with the email server, this kind of software is installed on the computer. The mailbox is checked for spam several times per hour, and every time unwanted emails are identified they are immediately deleted. Such spam blockers consume resources and bandwidth.
Spam blockers that are installed on the email servers are the common used tools available with MSN or Yahoo! Mail. Starting from potentially aggressive phrases, keywords or writing styles, the incorporated software detects the unwanted emails. Spam filters are definitely not infallible, and many dishonest Internet users have found ways to fool the filters.
Spam blockers could be a problem for Internet marketers that use opt-in listings to advertise their products and services. Lots of newsletters don’t get read because the spam filters or spam blockers treat them like unsolicited mail. Many marketers have found ways to adapt to this situation, managing to pass filters by changing the email content.
Statistically, spam blockers stops about 90% of the total number of unwanted messages, which in fact is a great way of preventing computer infections with the viruses that are often sent in such emails. There are even some modern anti-spam systems that can reduce 99% of spam.
Always test the compatibility of various spam blockers with your computer and the email service so that you don’t make a poor choice. Also make sure that you won’t have difficulties of installation, and find out how high the level of blockage is. The cost is also an issue as the most effective tools are the priciest on the market.
