Would You Spot the Red Flags in Your Inbox?

Phishing emails have become harder to spot. Attackers mimic your suppliers, your team, or even Microsoft. The red flags are still there—but they’re buried under fake branding, tone-matching subject lines, and rushed morning inboxes.

This guide walks through the most common email phishing red flags, and what you can do to protect your business. It’s for SME owners and managers, not IT specialists.

Why Email Is the Favourite Route for Attackers

Email is cheap. You don’t need to hack anything. You just need one click.

Cybercriminals often use phishing—emails designed to trick you into giving away login details, money, or data. It’s still the most common cause of business breaches.

10 Email Phishing Red Flags That Get Missed

These red flags don’t require technical knowledge—just a habit of checking before acting:

1. Strange sender email addresses
   Often one letter off or using odd domains, like micros0ft-support.com. Always check the full email address.

2. Urgency or pressure tactics
   Messages saying “Your account will be locked in 1 hour” are designed to panic you. Pause before responding.

3. Unexpected attachments or links
   A file you weren’t expecting or a link to a “secure document” is often bait. Don’t open or click unless you’re sure.

4. Requests for login info
   No real company asks you to confirm your password or login by email. This is a common phishing tactic.

5. Generic greetings and poor grammar
   Emails starting with “Dear customer” or containing basic errors signal a rushed or fake message.

6. Branding that looks almost right
   Logos and signatures copied from real businesses can still be fake. Don’t trust visuals alone.

7. Mismatch between display name and email address
   It might say “Finance Team,” but the email is from a random domain. Always check beyond the name.

8. Odd or unexpected timing
   A finance request at 3am or on a UK bank holiday should raise questions.

9. Unfamiliar invoices or payment demands
   Fake supplier emails often include realistic-looking invoices. Contact the real supplier before taking action.

10. Too-good-to-be-true offers
    Surprise refunds, gift cards, or offers with no context often lead to scams. Delete them.

Microsoft, Gmail, or Anything Else—Scammers Don’t Care

If your business uses Microsoft 365, scammers target it. It’s widely used and holds valuable access to business systems. But they send these attacks to all platforms—Google, Yahoo, private mail servers—using automated tools.

AI now helps scammers get more convincing. They scrape your website or LinkedIn and adjust tone, names, and timing to increase the chance of success.

No email system is immune.

Even Microsoft Defender or Google’s filters can’t catch every well-crafted phishing attempt. They’re useful. But you need user awareness too.

What You Can Do Right Now

Start by encouraging your team to pause before clicking. Most phishing emails rely on urgency—training people to stop and check is one of the simplest ways to reduce risk. You can also add a banner to emails that come from outside your organisation, which is easy to do in Microsoft 365. This gives staff a clear visual cue when something might need a second look.

Make it straightforward for people to report suspicious messages. A shared inbox or even a WhatsApp group for questionable emails can work. If you’re not already using multi-factor authentication (MFA), it’s worth adding—especially to accounts with admin access. MFA adds a layer of protection if login details are stolen. Check your existing email security settings too. Microsoft 365 includes anti-phishing policies that aren’t always turned on by default.

Finally, instead of long training sessions, send short reminders or examples each month. These are quicker for staff to digest and easier to stick with.
