Spam filters are used for detecting unwanted virus-infested emails and stopping them from entering email inboxes. Spam filters are used by Internet Service Providers (ISPs) to ensure that they are not distributing spam. These filters are also used by small- to medium-sized businesses (SMBs) for protecting their networks and employees.

Spam filters are applied to both outbound email (email leaving the network) and inbound email (email entering the network). Both these methods are used by ISPs to protect their customers. SMBs generally focus on inbound filters. A number of spam filtering solutions are currently available. They can be integrated into email software such as Microsoft Outlook, or hosted in the “cloud,” on computer servers.

How Email Spam Filters Work

Email spam filters are a series of multiple filters capable of evaluating an email as it comes in. In this evaluation process, the email spam filter looks into various parts and compares them to multiple lists and rules. Some of the most common filters include:

  • Content filters: These filters weigh and measure all content, from the subject line to the footer. Spam filters focus on detecting flagged keywords, phrases, and even excessive punctuations.
  • User and permission filters: It is possible for individual users to apply additional filters to their spam, either by setting permission filters, adding rules, or flagging emails as spam.
  • Blacklists: IP addresses and domains that send out too many emails that are flagged as spam can become blacklisted with all future emails being hard bounced or going to spam. These emails affect IP and sender reputation, which eventually affect email acceptance.
  • Header filters: The header will have to be a valid email. Email platforms have standards compliance and user authentication in order to validate if the email is genuine or a fake one.

Why is Spam Filtering Important for Your Business?

Getting rid of spam is a vital step in any business because spam can take up too much of your inbox space and also a lot of your time when you begin to clear and remove all the spam from your inbox. Your company security and data can also get compromised by these spam emails that carry viruses and malware. The best solution for preventing such disasters is to use spam filters that can stop spam from inundating your work email and compromising your company’s security.

Spam filtering is thus an important tool for your business as it helps in blocking unwanted messages from entering your inboxes and preventing people from clicking on potentially harmful emails. Sometimes, we find that more than half of the emails we receive are actually classified as spam or junk. This highlights the fact that there is a huge potential for security issues because of these messages, and also a drop in productivity levels as people start spending too much of their time on deleting such spam emails from their inbox.

How to Avoid Email Spam?

To protect your business and its reputation, you will have to choose a spam filter based on the amount of email you and your employees receive every day. You should go in for an email spam filter based on the types of emails sent and received, and your company’s requirements and preferences.
