How to Recognize Spam and Phishing Emails

Spam and phishing emails are everywhere, and spotting them before you click a link or download an attachment can save you from malware, data theft, and financial loss. This guide shows you the key red flags to look for, how to inspect email details safely, and what to do when you’re unsure. You don’t need any special tools—just your email client and a few minutes of attention.

What You’ll Need

• Access to your email inbox (webmail, desktop client, or mobile app)
• The ability to hover over links without clicking them (on desktop) or press and hold on mobile to preview the URL
• A willingness to check the sender’s full email address and the message headers if needed

Step-by-Step

1. Check the sender’s email address, not just the display name. Scammers often set the display name to something trustworthy like “PayPal” or “Your Bank,” but the actual email address will be a random string of letters or a misspelled domain (e.g., support@paypa1.com or admin@bank-secure-alert.net). Hover over the sender name or click the dropdown arrow to see the full address.
2. Look for a generic greeting. Legitimate companies usually address you by name. Emails that start with “Dear Customer,” “Dear User,” or “Hello,” especially from a service you use, are a red flag—though not absolute proof, as some automated emails do use generic greetings.
3. Hover over every link before clicking. Move your mouse over any button or hyperlink (without clicking) and look at the URL that appears in the bottom-left corner of your browser or in the status bar. If the link doesn’t match the supposed destination—for example, a “Reset Password” button that points to bit.ly/xyz or some-random-site.net—do not click it. On mobile, press and hold the link to see the preview.
4. Check for urgent or threatening language. Phishing emails often create a false sense of urgency: “Your account will be suspended within 24 hours,” “Unauthorized login detected,” “You must verify immediately.” Scammers want you to act fast without thinking. Legitimate companies rarely use this tone, and they never ask you to click a link to “avoid” a penalty.
5. Inspect the spelling and grammar. Many phishing emails come from non-native speakers and contain awkward phrasing, typos, or inconsistent formatting. Watch for odd word choices, extra spaces, or a mix of fonts. While some scams are well-written, poor language is still a common clue.
6. Look for requests for personal information or credentials. A legitimate company will never ask you to reply with your password, PIN, credit card number, or Social Security number via email. If an email asks you to “confirm” or “update” such data by clicking a link, it’s almost certainly a phishing attempt.
7. Check for suspicious attachments. Unexpected attachments, especially with extensions like .zip, .exe, .scr, or .docm, are dangerous. They can contain ransomware or keyloggers. If you weren’t expecting a file, don’t open it—even if the sender looks familiar.
8. Verify the domain in the email’s links. If the email claims to be from your bank, the link should contain the bank’s official domain (e.g., bankofamerica.com), not a lookalike like bankofamerica.secure-login.com or bank0famerica.com. Look for typos or extra subdomains.
9. Check the email headers (optional but thorough). In Gmail, click the three dots next to the reply button and select “Show original.” In Outlook, open the email and go to File > Properties. Look at the “Received” fields—the domain in the first “Received” should match the sender’s domain. If it’s from a random IP or country, it’s likely spoofed.
10. When in doubt, contact the company directly. Instead of clicking any link in the suspicious email, go to the company’s official website (type the URL yourself) or call their official customer service number. Ask if the email is legitimate.

Common Mistakes

• Trusting the display name. The most common mistake is assuming the sender is legitimate because the name shows “Apple” or “Microsoft.” Always verify the actual email address.
• Clicking links out of curiosity. Even if you don’t enter any data, clicking a phishing link can trigger a drive-by download or take you to a fake login page that steals your session cookie.
• Assuming spam filters catch everything. Some phishing emails land in your inbox, especially if the sender has used a compromised account or a new domain. Your inbox is not a guarantee of safety.
• Opening attachments on mobile. Mobile devices are just as vulnerable as computers. An attachment can install malware that steals your contacts or banking info.
• Ignoring the “this email was sent from outside” warning. Many corporate email systems add a banner for external senders. If you see that, treat the email with extra suspicion.

Tips

• Enable two-factor authentication (2FA) on your important accounts. Even if a phisher gets your password, they still can’t log in without the second factor.
• Use a password manager. It will automatically fill in credentials only on the correct domain, so if you land on a fake site, it won’t autofill—and that’s a clear warning.
• Keep your email client and operating system updated. Security patches often fix vulnerabilities that phishing links exploit.
• Report suspicious emails. In Gmail, click the three dots and choose “Report phishing.” In Outlook, use the “Report Message” add-in or forward the email to your IT department if it’s work-related.
• If you receive a suspicious email from a friend’s address, contact them via another channel (like phone or text) to confirm they sent it. Their account may have been hacked.

Troubleshooting

What if I already clicked a link or opened an attachment?

• Disconnect your device from the internet immediately (turn off Wi-Fi or unplug the Ethernet cable). This can stop malware from communicating with its command server.
• Run a full antivirus scan with your security software.
• Change the passwords for any accounts you may have entered on the fake page, and do it from a different, known-secure device.
• Enable 2FA on those accounts if you haven’t already.
• If you entered financial information, contact your bank or credit card company right away to freeze the card or monitor for fraud.
• If it’s a work email, notify your IT department immediately—they may need to quarantine other emails or check for network compromise.

What if the email looks completely legitimate?

• Even the most convincing email can be a scam. The safest approach is to never click a link in an email that asks for personal information or action. Instead, go directly to the official website by typing the URL into your browser.
• If you’re still unsure, call the company using the number on your statement or their official website—not the number in the email.

Frequently Asked Questions

What is the difference between spam and phishing?

Spam is unsolicited bulk email, often for advertising or scams, but it doesn’t necessarily try to steal your information. Phishing is a targeted attempt to trick you into revealing personal data or installing malware. All phishing is spam, but not all spam is phishing.

Can phishing emails contain viruses even if I don’t click anything?

Simply opening an email is generally safe—modern email clients don’t run scripts just by displaying the message. However, clicking a link or opening an attachment is where the danger lies. Some emails use “tracking pixels” that can tell the sender you opened the email, but that’s not harmful.

Why do phishing emails often have typos?

Typos and grammatical errors are sometimes intentional. Scammers know that people who notice these mistakes are less likely to fall for the scam, so they filter themselves out. This leaves the most vulnerable targets—those who don’t notice the errors—as the ones who are more likely to respond.

Is it safe to unsubscribe from spam emails?

For legitimate marketing emails, unsubscribing is safe. But for phishing emails, clicking the unsubscribe link can confirm your email address is active, leading to more spam. If the email looks like a scam, don’t click any links—just mark it as spam and delete it.

How can I tell if an email is really from my bank?

Check the sender’s email domain. Banks use their official domain (e.g., @chase.com). They never send from Gmail, Yahoo, or a domain that looks like a misspelling. Also, banks never ask you to click a link to verify your account—they typically ask you to log in to your online banking directly.

What should I do if I accidentally entered my password on a phishing site?

Change that password immediately, and if you used the same password elsewhere, change it there too. Enable 2FA on all important accounts. Monitor your accounts for suspicious activity. If you entered credit card details, contact your bank to place a fraud alert.
