How to spot phishing emails: 3 subject line red flags you can’t ignore

Your email inbox is a favorite hunting ground for cybercriminals. Every day, they send out thousands of phishing emails, hoping to trick you into clicking a malicious link or giving away your login credentials. These emails are usually carefully crafted to look like authentic communications from trusted brands like your bank, Amazon, or even your internal IT department.

But here’s the good news: while phishing scams are getting more sophisticated, they still give themselves away in subtle ways. You don’t have to open the email or click a link to spot the danger. Often, the first and most critical warning sign is right there in the subject line.

You need to train your eyes to spot the warning signs before you engage with the message.


Three Subject Line Tactics That Scream “Scam”

Criminals rely on a combination of panic, pressure, and poor grammar to make their schemes work. Look at the subject line closely for these three massive red flags:

1. The Urgency Trap (All Caps)

If a subject line is SCREAMING at you in all capital letters, or uses overly dramatic language, your immediate response should be skepticism. Examples include:

  • ACTION REQUIRED!
  • YOUR ACCOUNT HAS BEEN FROZEN IMMEDIATE ATTENTION NEEDED
  • WARNING PAYMENT DECLINED

Legitimate companies rarely use all caps. They want to be professional and reassuring. Hackers use all caps and urgent phrasing because they want you to panic and click before you think. If you see an all-caps call to action, don’t engage. Instead, navigate directly to the company’s official website to check your account status.

2. The Personalized Peek (Your Email Address)

This is a tactic designed to make the email look hyper-specific to you, forcing you to pay attention. If the subject line includes your actual email address, it is a huge warning sign.

  • [YOUR EMAIL ADDRESS] Order Confirmation
  • PASSWORD RESET FOR [YOUR EMAIL ADDRESS]
  • ATTENTION: Action Required for [YOUR EMAIL ADDRESS]

Why would a company already sending an email to your address need to repeat that address in the subject line? They wouldn’t. This is a common tactic used by criminals who harvest email lists and try to make the message seem instantly authentic.

3. The Sense of Dread (Threats)

Phishing scams often threaten negative consequences unless you click now. Look for words like “Suspended,” “Expired,” “Deactivated,” “Penalty,” or “Legal Action.”

If your bank is going to suspend your account, they will usually notify you through secure communication channels, not a frantic, poorly worded email.

Your Active Solution: Read and Delete

Make it a habit to scrutinize subject lines before you even open the email:

  • Pause and Ask: Is this expected? Did I just order something?
  • Scan for Errors: Look for spelling mistakes or poor grammar that a professional company would never miss.
  • Don’t Click to Unsubscribe: If it’s a piece of spam you want to get rid of, don’t click the unsubscribe link in a suspicious email—it just confirms your address is active. Mark it as spam or junk.

By actively watching your subject lines, you stop the threat at the gate, keeping your inbox clean and your data safe.
