When choosing a spam email filter, consider cost and compatibility with your mail program. Some filters use a blacklist or keyword scan, while others use a white list or user-set rules. It takes time for the program to learn which messages are spam, so regularly check your Junk mailbox.
To choose the best spam email filter, you’ll first need to determine how much you want to spend on this type of computer program; there are some free options, as well as more aggressive options that are more expensive. You will also need to check that your spam email filter is compatible with the mail program you use, as not all programs will be compatible with all filters. Additionally, these programs typically require an initial investment of time as they “learn” what you consider spam and what is legitimate email.
Some anti-spam email filter programs will simply filter emails based on a constantly updated list of known spammers, while others will rely on a quick scan of the email content to detect certain keywords that typically indicate spam. These are the simplest types of spam filters, and most email programs will have a built-in spam filter that works with these parameters. Many people find that they end up with a large amount of spam in their inboxes, however, when purchasing a commercial spam email filter it might be a good idea.
There are several types of spam email filters, some more aggressive than others. Two of the most aggressive spam blockers are those that use a “white list” to deliver email to the mailbox; the user will enter the email addresses of the people they want to receive emails from and all the others will be marked as spam. Some programs will even force every person who sends you an email to reply to an automatically generated message with a code to ensure it’s a real person sending the email and not a spammer. These types of programs are obviously quite effective, but they can lead to frequent lost emails.
The most popular type of anti-spam email filtering is one that is based on a combination of the spammer blacklist and keyword restrictions mentioned above, as well as user-set rules. These programs typically take a few weeks to set up, as the program “learns” which messages you consider spam and which are legitimate. The user will go through e-mail every day, marking some as spam, and over time the program will be able to identify them without user input. It’s important to check your Junk mailbox regularly to make sure legitimate messages aren’t being sent there by mistake.
