Email spam is not just a headache in an inbox, it has a detrimental impact on productivity, security, and overall company performance. The average daily volume of spam is a staggering 282.9 billion messages. Within this haystack of spam lies the needle prick of phishing emails that can end up causing massive damage to a company, in the form of lost revenue, stolen credentials, and damaged reputation. To deal with the onslaught of spam, companies the world over are turning to spam filtering solutions to provide email protection.
The most dangerous form of email spam is phishing. According to Microsoft’s Security Intelligence Report (SIR), phishing is the number #1 way that malware, including ransomware, infects endpoints and networks. The report shows that over half of emails that land in an inbox are a result of phishing campaigns.
Unfiltered email results in a large amount of spam and phishing emails entering individual employee inboxes. Employees are drowning in spam emails and the company is under threat from phishing. Email spam solutions and email protection solutions are designed to prevent email spam and phishing messages from entering a user’s inbox.
The impact from unfiltered email is trifold:
Spam email in large numbers is a numbing experience: in July 2021, the average employee received over 81 emails per day. Mixed in this email onslaught are spam, phishing, and legitimate messages.
These emails are often opened on mobile devices (37% opened on an Apple iPhone as of July 2021), the UI making it more difficult for an employee to spot a fake email. Employees may miss important emails; legitimate emails being lost in the noise of spam. Even a few minutes wading through spam emails adds up to lost productivity.
Email filters prevent spam noise by stopping spam emails from entering an employee's inbox.
In 2020, 74% of U.S. organizations were a victim of phishing. Spam is more than just annoying, they can contain dangerous routes to malware infection and/or credential theft. Employees inundated by spam must make fast decisions.
Even the more security-aware employee can end up clicking on a phishing link without thinking. Automated clicking makes computing quicker and simpler, and the more intuitive it becomes the more automated our behavior is; in other words, human beings are conditioned to click on links.
Email spam filtering solutions break the chain to automated click behavior by removing the source, i.e., the spam email.

Spam emails result in serious financial losses for an organization. The data breaches that a phishing attack can lead to are, on average, $4.24 million according to a 2021 IBM study. Ransomware has increased by 40% in 2020, and often begins with a phishing email. Ransomware costs doubled in 2021 to, on average, $1.85 million per company.
The costs of a click on a malicious link all add up. Costs accrued by a data breach and ransomware damages, include damage to reputation, share price decline, system downtime, lost productivity, and data protection fines.
The $10 a head per year cost of a cloud-based email filtering solution, compares well to the cost of a data breach.
An email filtering solution prevents malicious massages and general spam from landing in an employee's inbox, removing the threat at the source. Email spam filtering solutions are designed to automatically work out which incoming messages, detecting which are spam and which are legitimate messages.
Some email spam filtering solutions also check outbound emails for spam and viruses to prevent the organization´s IP addresses from being blacklisted, causing productivity issues, and impacting reputation. Advanced spam filters, such as SpamTitan, also allow certain data types to be tagged, for example, Social Security number. In doing so, the spam filter prevents sensitive data from being leaked via email.
