Getting rid of junk mail wastes your time and tries your patience. Especially if your e-mail system has limited storage capacity, spam e-mail can cause you to miss an important message. The risks don’t end there. Aside from ads on products that you don’t really want, spamming is also a popular method cyber criminals use to phish. Free your inbox—and yourself—of spam now. Here are some tools you can use to ward off spam for good:
Purpose of email spam fighters
There are ways to keep spam off manually, like dismissing e-mails from unknown senders, safekeeping your e-mail address, and never responding to mails you suspect as spam. However, spammers are becoming more resourceful and creative. Unless you’d rather spend the first hour of your work day deleting junk from your inbox, the best thing for you to do is to install or sign up for a spam-fighting tool. They block, reject, filter out, and perform many other actions against spam to keep it from reaching your inbox.
Basic types of email spam fighters and how they work
Most webmail services today have effective built-in spam protection, such as Yahoo! Mail’s customizable SpamGuard and Gmail’s multiple authentication system. There are several kinds of anti-spam tools: authentication systems, such as Sender Policy Framework and DomainKeys; filtering systems, such as challenge/response, checksum-based, and country-based filters; and DNS-based Blacklists. Generally, these tools combat e-mail spam by checking the reputation of the source site and setting parameters against which the content or contact information of received e-mails are tested.
Aside from being a time-waster, spam e-mail can expose you to malware, phishing, and fraudulent transactions. To safeguard yourself against these risks, get a good anti-spam program, especially if you’re unsure if your e-mail system has internal spam protection.
