Spam filters are a safety feature for many modern institutions that use emails as part of their operations, whether to transfer internal information to colleagues or communicate externally with contractors and customers. Spam filter aims to protect users from unwanted, potentially virus-infected emails.
Why Use a Spam Filter?
Time needed: 1 hour.
There are many reasons to use a spam filter. Here are the most common reasons for filtering emails for spam;
- Security
Avoiding virus-infested emails is vital for maintaining the health of your IT systems. Phishing emails are the most common form of email virus and aim to steal as much personal information from any source as possible.
- Efficiency
When sorting through work emails, it is far easier only to have to work through ones relevant to your job. By using spam filters, all of the unwanted email advertising campaigns from companies you have never visited become separated, leaving your inbox more organized and more accessible to sort through.
- AI that learns which emails you don’t want to receive
Some spam filters even expand their list based on emails that the user often deletes without reading. If your email marketing emails are often unread before being deleted, you risk becoming marked as spam.
Filters Used by Spam Filters
Spam filters use many different filters to detect spam. These include; content, blacklist, headers, language, rule-based, and bayesian. These filters monitor your emails and behavior with them. They learn and adapt based on which emails you add to the spam folder and which you seek out and add back to your inbox. Bayesian filters are responsible for learning your preferences and marking senders you repeatedly delete as spam. All of these filters are very good at spotting patterns and protecting their user from any suspicious emails that are potentially full of malware or other viruses.
Spam Filter Apps
There are also apps available to provide extra spam filtration. It is important to choose a trustable app to use because the app will have access to your emails and any information provided from them. These spam filter apps can also block any unwanted SMS messages or callers from numbers known to be spam. These apps offer the same service as email spam filters do, just on a larger scale and across multiple devices. Check the services provided by each app, as well as their ratings, and then select the app that best suits your needs. The fact that there are now multiple high-quality apps for spam filtration indicates just how quickly this branch of technology continues to adapt, grow, and evolve with new products as well as services.
Conclusion on Spam Filters
To conclude, spam filters are a handy feature for email services. They prevent many unwanted emails from reaching their customers and can even adapt to their user’s needs. By using spam filters, companies reduce the amount of time their employees spend deleting unwanted emails while simultaneously protecting themselves from many viruses. Not only do spam filters offer protection from virus-infected emails, but they also get rid of any unsolicited marketing emails.
