Thus, spam filters become necessary and unavoidable. Here is the list of the 9 best spam filters for you to stay secure.

Why You Need an Effective Spam Filter?

Research shows that 14.5 billion spam emails are sent every single day, earning their senders a daily average of $7,000. According to the same research, 46% of emails are spam. That’s a lot of potentially-dangerous messages!

An effective spam filter will protect email recipients from potential threats that come from spam emails. They have the potential to block the likes of viruses, and phishing attacks, and segregate safe emails from spammy ones.

How do Spam Filters Work?

Spam filters are available in the form of software, hosted, or an on-premise appliance. They work by analyzing your emails before they reach your inbox to determine if they are spam or not. They analyze the content, email address, header, attachments, and language of your emails, and scan them for anything “suspicious”.

For example, if the language in the email does not match your own, they have the capability of marking that as spam.

Emails sent from known spammers will be black-listed, and so spam filters will check emails against this too.

Free Spam Filters VS Paid Spam Filters

Your email host will usually have a spam filter built in whether you’ve opted for a low-cost VPS provider for your business, or you have a more expensive and complex package. Most email hosts provide the same “free” degree of spam filtration and security.

This is why some of your emails get sent straight to your spam folder. It’s a very basic filter and often times you will get spam in your inbox and vice versa. This results in regular trips to your spam folder to see whether you’ve missed any important emails or promotions via email marketing.

Downloading free anti-spam software will have a similar effect, but it will be slightly more advanced. And, you may have more features and options available to you.

These may be ideal for personal use, however, for businesses, particularly those with multiple employees, computers, and email accounts, they won’t hold their own.

A paid-for spam filter will give your company computers and email accounts for the best protection. They will be more thorough in their scanning and analyzing processes.

Your employees, while at work, are your responsibility. If they fall victim to a scam while under your care because you didn’t put the proper precautions in place, the fault could fall on you. Equally, it can prove costly to rid computers of viruses obtained from spam emails.
