How to Stop Spam Before It Stops Your Business
Spam isn’t just annoying anymore, it’s dangerous. What used to be harmless junk mail has evolved into one of the most common entry points for cyber criminals. Today’s spam can look like an invoice from a trusted supplier or a delivery update from a familiar courier. Behind these emails are scammers aiming to:
- Steal passwords and banking details
- Infect your systems with malware
- Trick staff into transferring money or granting access
And they don’t just target big corporations. Small and medium-sized businesses are prime targets because they often have fewer defences in place.
Why Spam Filtering Matters
Every email is a potential doorway to your business. Spam filtering acts as your first line of defence, a bouncer for your inbox. It checks every incoming message and blocks anything suspicious before it reaches your team. A good spam filter can stop over 99% of harmful emails, protecting your data, money, and reputation.
How Spam Filters Work
Modern spam filters use multiple layers of protection:
- Reputation checks: Blocks known spammers instantly
- Content scanning: Detects suspicious language, links, and attachments
- AI and machine learning: Adapts to new threats automatically
- Link and attachment analysis: Stops hidden malware before it spreads
- User feedback: Learns from what you mark as spam
Setting Up Spam Filtering
Start with what you already have, platforms like Microsoft 365 and Google Workspace include basic spam protection. Then add extra layers for advanced phishing detection and attachment sandboxing. Customise your rules, maintain allow/block lists, and review quarantined emails regularly.
Your People Are Key
Even the best technology can’t catch everything. Train your team to spot red flags:
- Check the sender address carefully
- Be wary of urgent or fear-based messages
- Hover over links before clicking
- Avoid unexpected attachments
Encourage reporting and create a “no blame” culture. Regular reminders and phishing simulations keep awareness fresh.
Stay Ahead
Spam filtering isn’t a one-time job. Keep systems updated, monitor reports, and review settings regularly. Partnering with an IT support team ensures everything runs smoothly, giving you peace of mind and a safer inbox.
