How to Spot a Phishing Email Before It Costs Your Business
It usually starts with something small.
An email that looks routine. An invoice waiting to be paid. A missed delivery notice. A quick request from a colleague to "review this when you get a chance."
Nothing about it feels obviously wrong. So you open it. Maybe you click the link. Maybe you download the attachment. Maybe you just reply without thinking twice.
And that's all it takes.
Phishing attacks don't succeed because of technical weaknesses. They succeed because people are busy, distracted, and dealing with hundreds of messages a day. The uncomfortable truth is that most phishing emails no longer look like scams — they look like work.
Why Phishing Still Works (Even When People Know About It)
Ask anyone in your team if they know what phishing is, and they'll say yes. But awareness hasn't kept pace with how convincing these emails have become.
Gone are the days of obvious spelling mistakes and broken formatting. Today's phishing emails are well-written, well-timed, and tailored to look exactly like the messages you'd expect to receive on any given day.
They commonly impersonate:
- Suppliers sending invoices
- Delivery companies with tracking updates
- Internal colleagues asking for urgent help
- Trusted platforms like Microsoft 365 or your bank
And they all share one common ingredient — urgency. That's deliberate. When people feel rushed, they stop questioning what they're looking at.
The Subtle Signs Most People Miss
Spotting a phishing email isn't about finding one obvious red flag. It's about noticing the small inconsistencies.
The sender address. At a glance it might look legitimate, but a closer look often reveals something slightly off — a missing letter, an extra character, or a domain that doesn't quite match the real one.
The tone. Does the message feel unusually urgent? Is it pushing you to act before you've had time to think? That's a common tactic.
The links. Hovering over a link (without clicking) will often reveal a destination that doesn't match what's shown in the email.
The attachments. Unexpected files — especially invoices, PDFs, or documents you weren't expecting — should always raise a question.
No single signal confirms a phishing attempt on its own. But together, they tell a story.
Why Familiarity Is the Real Risk
Phishing works so well because it blends into everyday business activity.
If your team regularly receives invoices, an invoice email doesn't feel suspicious. If you use Microsoft 365, a login prompt doesn't feel unusual. Attackers rely on that familiarity. They don't need to invent something new — they just need to imitate what's already happening in your business.
That's why even careful, experienced staff get caught out. It's not about being careless. It's about being human.
What Happens When Someone Gets It Wrong
There's a tendency to think of phishing as a minor issue. Click a bad link, realise the mistake, move on.
But in reality, the impact can escalate fast. Credentials get captured. Email accounts get accessed. Attackers then use that access to send convincing messages internally or to your clients — often resulting in fraudulent payments transferred based on what appears to be a perfectly legitimate request.
By the time it's spotted, the money is usually long gone.
Building Better Habits
The goal isn't to make your team paranoid. It's to make them pause.
A few simple habits go a long way:
- Take a moment before acting on unexpected emails
- Double-check sender addresses, not just display names
- Avoid clicking links directly — go to the source manually if unsure
- Question urgency, especially around payments or credentials
If something feels slightly off, it's worth checking. No legitimate request will fall apart because someone took an extra minute to verify it.
This Isn't Just an IT Problem
Phishing can't be solved with technology alone. Filters help. Security tools help. But they don't catch everything.
At some point, a phishing email will land in someone's inbox. What happens next depends entirely on the person reading it. That's why awareness — and more importantly, behaviour — matters.
Final Thought
Phishing emails don't succeed because people are uninformed. They succeed because people are busy. They look like normal work. They arrive at the wrong moment. And they rely on quick decisions.
The difference between a close call and a costly mistake is often just a few seconds of attention.
In most cases, that's all it takes to stop it.
