How to Spot a Phishing Email: A Practical Guide for Businesses
Most of us are not falling for the email promising a free $100 Amazon gift card anymore.
Unfortunately, scammers know that too.
Now, the email may look like it came from your boss asking whether you are available for a quick favor. It may appear to be a Microsoft 365 password-expiration notice, a shared document from a coworker, an overdue invoice from a vendor, or a voicemail notification waiting to be opened.
The message may look professional. The company logo may be correct. The grammar may be better than some legitimate emails we receive.
That is what makes modern phishing so effective.
Artificial intelligence has made it even easier to create polished, convincing messages. The National Institute of Standards and Technology recommends taking another look at messages requesting that you click a link, download a file, transfer money, sign into an account, or provide sensitive information.
You do not need to become a cybersecurity expert before opening your inbox. You just need to recognize when an email deserves a pause.
What Is Phishing?
Phishing is a form of social engineering, which is the technical way of saying that someone is trying to manipulate you into doing something you normally would not do.
The attacker may want you to:
Enter your username and password on a fake website
Provide a multi-factor authentication code
Open an infected attachment
Approve a payment or wire transfer
Change a vendor’s banking information
Share confidential business or customer information
Install malicious software
These messages are usually disguised as something familiar: your bank, Microsoft, a vendor, a delivery company, an executive, or another employee.
Warning Signs That Deserve a Second Look
No single warning sign automatically proves an email is fake. However, the more unusual details you notice, the more carefully you should investigate.
1. Everything Is Suddenly an Emergency
Your account will be deleted in 30 minutes.
“Your account will be deleted in 30 minutes.”
“The invoice must be paid today.
“The CEO needs gift cards before the next meeting.”
“I don’t have time to talk, please handle this quietly.”
Phishing messages often create urgency because people make different decisions when they feel rushed.
If the message is trying to prevent you from stopping and thinking, stop and think.
2. The Name Looks Familiar, but the Address Does Not
An email can display the name of your CEO, bank, vendor, or coworker while coming from a completely unrelated address.
Always check the actual email address.
Watch for:
Misspelled domain names
Extra letters or numbers
Free Gmail or Outlook addresses
Slight variations of a legitimate company address
A reply-to address that does not match the sender
A familiar name and company logo are not proof that an email is legitimate. Anyone can copy a logo.
3. You Were Not Expecting the Link or Attachment
“Someone shared a document with you.”
An unexpected invoice arrives from an unfamiliar company.
A voicemail notification asks you to download an audio file.
Before clicking, ask yourself whether the message makes sense in the context of your actual work.
If it claims to come from Microsoft 365, your bank, or another online service, open a fresh browser window and visit the website directly. Microsoft will not be offended that you ignored the convenient email button.
4. Someone Wants Your Password or Login Code
Your password and multi-factor authentication codes should be treated like keys to the building.
A legitimate IT provider should not ask you to email your password. You should also never send someone a one-time code or approve an unexpected login notification.
If an authentication request appears when you are not signing in, deny it and notify your IT team.
5. Money Is Involved
Payment requests deserve extra attention, especially when someone wants to change the normal process.
Be cautious of requests involving:
Wire transfers
Gift cards
Updated vendor banking information
Urgent invoice payments
Payroll or direct-deposit changes
Verify the request using a phone number or communication method you already trust.
Do not call the number listed in the suspicious email. That is like asking the person wearing the fake mustache whether the mustache is real.
6. The Request Does Not Follow Normal Procedure
Sometimes the email looks fine, but the request itself is unusual.
An executive asks you to bypass the normal accounting approval.
A vendor requests payment to a new account.
An employee requests a payroll change without the usual paperwork.
Processes may occasionally feel inconvenient, but they exist for a reason. An email should not be allowed to override an established approval procedure.
How to Verify an Email Safely
You do not need to conduct a forensic investigation.
Use a different, trusted communication method:
Call the sender using a phone number you already have.
Message the person through your usual business platform.
Visit the organization’s official website directly.
Ask your IT provider or internal IT team to review the email.
Confirm financial requests through the normal approval process.
A quick “Did you send this?” can save hours—or days—of recovery work.
What If Someone Already Clicked?
First, do not panic. Second, do not hide it.
Employees should report suspicious activity immediately if they:
Clicked a questionable link
Opened an unexpected attachment
Entered a username or password
Approved a login request
Shared a verification code
Sent sensitive information
Completed a suspicious payment
Contact the IT team and explain exactly what happened. Do not leave out details because they feel embarrassing.
Depending on what occurred, the response may include securing the device, changing passwords, ending active sessions, checking account activity, reviewing email-forwarding rules, or contacting a financial institution.
The sooner the incident is reported, the more options the response team has.
Businesses should also avoid making employees feel as though they have confessed to sinking the company. If people are afraid to report mistakes, they will wait, and waiting can make the situation much worse.
Employees Should Not Be the Only Line of Defense
Training matters, but even careful people can be fooled by the right message on the wrong day.
Businesses should use several layers of protection, including:
Email filtering
Multi-factor authentication
Endpoint protection
DNS filtering
Managed threat detection
Security monitoring
Password-management tools
Regular software updates
Employee security training
Tested incident-response procedures
Reliable backups
No single tool can stop every phishing attempt.
The goal is to reduce the number of malicious messages reaching employees, make stolen credentials harder to use, and respond quickly when something gets through.
Make It Easy to Ask for Help
Every employee should know:
How to report a suspicious email
Who to contact after clicking
What information the IT team needs
What to do outside normal business hours
When reporting is confusing, people hesitate.
The company should create a culture where asking, “Is this email legitimate?” is treated as responsible, not annoying.
We would much rather review ten legitimate emails than respond to one successful phishing attack.
Pause Before You Click
Phishing emails depend on urgency, distraction, and trust.
The next suspicious message may not offer you a free gift card or claim that a distant relative left you millions of dollars. It may look like an ordinary part of your workday.
Pause. Check the sender. Consider the request. Verify it through a trusted method.
That extra minute may protect your accounts, your data, and the rest of your organization.
