Key Takeaways

Phishing emails often contain grammar and spelling errors, indicating they may not come from a legitimate source.
An unfamiliar tone in an email can be a red flag for a phishing attempt, especially if it doesn’t match your usual communications.
Receiving emails at unusual times can signal a potential phishing attempt, particularly outside normal working hours.
A sense of urgency in an email may pressure you to act quickly, which is a common tactic used in phishing schemes.
Suspicious attachments in an email can lead to malware infections, so it’s crucial to avoid opening them without verification.

Phishing emails remain one of the most common and dangerous cyber threats today. Attackers exploit human trust by using convincing messages that appear to come from trusted sources, and they often create a false sense of urgency to prompt you into clicking a link or sharing sensitive information without hesitation. What makes phishing especially dangerous is the growing sophistication of these attacks. They no longer rely on obvious spelling mistakes or generic greetings, but instead use realistic branding, personalized details, and even advanced social engineering tactics.

Because of this, learning how to spot phishing indicators early is more important than ever. Recognizing the subtle signs of a phishing attempt can help you protect not only your personal data but also your entire organization from costly breaches and reputational damage.

Common Phishing Indicators

One of the most important things you can do as a business owner is to protect your data. If someone gains unauthorized access to your systems, they could steal or alter sensitive information, such as credit card data and personal records. It’s increasingly common for legitimate business owners to be targeted by phishing attacks. In addition to leveraging anti-phishing solutions, understanding the signs of a phishing attempt or phishing indicators allows you to spot scams early and prevent them from being successful. Here’s what to look out for when protecting your company from phishing attacks.

Now let’s get down to the most common phishing indicators of a phishing attempt:

1. Grammar and spelling errors

A common indicator of a phishing attempt is the presence of grammar and spelling errors in the email content. The reason for this is that most emails originating from an untrusted source are not written by professionals. This means that there are no spell check features on their servers, and no proper proofreading or editing process.

In contrast to this, professional businesses are careful about spelling in their outbound email marketing communications. Plus, they have professional copywriters to craft their email marketing messages and usually use a grammar checker to quickly find and fix all kinds of mistakes in their emails before sending them.

Some common grammar and spelling errors in phishing emails are:

➜ Missing quotation marks (‘), periods (.), commas (,) and colons (:)

➜ Incorrect capitalization of words or phrases (e.g., “i am Bob”)

➜ Informal contractions like “u” instead of “you”

➜ Strange or unnatural phrasing that doesn’t sound fluent

➜ Basic spelling mistakes (e.g., “recieve” instead of “receive”)

➜ Awkward sentence structures that seem machine-translated

2. Unfamiliar tone

An unusual or inconsistent tone in an email can also signal a phishing attempt. Sometimes, the wording feels slightly “off,” as if the sender doesn’t really know you. For instance, you might receive a message from a colleague that sounds far too formal, or an email from your bank that uses casual, chatty language you wouldn’t normally expect.

Another red flag is when the message doesn’t match your situation. If you suddenly receive an urgent notice about an overdue payment or account issue that doesn’t apply to you, it’s worth treating the email with suspicion. When in doubt, always verify directly with the supposed sender using official contact details rather than replying to the suspicious email.

3. Unusual time

If you receive an email at a time that is unusual for you to be receiving messages from the sender, this can be another phishing indicator. For example, if you are used to getting work-related emails during normal business hours but suddenly get a message from your boss after 11 p.m., that could raise suspicion. Likewise, an email arriving in the middle of the night on a Saturday or Sunday may not align with your typical communication patterns.

It is important to note, however, that a late-night or early-morning email is not always a scam. Many people work flexible schedules, travel across time zones, or simply keep different hours. What makes the timing suspicious is when it appears alongside other red flags, such as:

➜ The email contains urgent demands (for example, “transfer funds immediately”).
➜ The sender’s tone or style does not match what you usually expect from them.
➜ There are grammar, spelling, or formatting errors that look unprofessional.
➜ The message includes unexpected links or attachments.

Attackers often send phishing emails at unusual times, such as early in the morning, late at night, or on weekends. They do this because recipients may be tired, distracted, or less likely to scrutinize details carefully. When you notice odd timing combined with other warning signs, it is safer to pause and verify the email through a trusted channel before taking any action.

4. Urgent or threatening language

Another common sign of a phishing email is the use of fear and urgency to pressure you into acting without thinking. Attackers rely on this psychological trick because when people feel stressed or rushed, they are less likely to scrutinize details or question the legitimacy of a message. By creating a sense of panic, scammers hope you will react instantly instead of carefully verifying the request.

Some common tactics include:

➜ Threats: Warnings that your account will be suspended, your data will be deleted, or legal action will be taken if you do not comply.
➜ Tight deadlines: Demands that you respond within 24 hours or even minutes to avoid negative consequences.
➜ Alarming subject lines: Messages titled “Account Suspended,” “Urgent Security Alert,” or “Immediate Action Required” designed to grab your attention and trigger anxiety.

If an email makes you feel like something bad will happen unless you act right away, treat it with caution. Always verify the claim through official channels before clicking any links or sharing information.

5. Suspicious Attachments

A common indicator of a phishing attempt is a suspicious attachment. The bad guys often use phishing emails to send these attachments because they know many people are curious enough to open them and click on whatever links or buttons they contain.

These attachments may be a Word document or zip file, for example. But if you open the attachment and it’s malicious, it could infect your computer with malware that steals your login credentials. If you get an email with a suspicious attachment, don’t click on it!

*Although it’s best to scan attachments for viruses before opening them, some email providers— like Gmail and Yahoo —have incorporated advanced checking filters that will automatically show the attachment in question as ‘Blocked Attachments’ if found suspicious.

6. Too good to be true offers

Scammers often exploit human curiosity and excitement by promising something unusually valuable. The idea of winning money, receiving a prize, or unlocking an exclusive deal can be so tempting that it lowers your guard and makes you less critical of the message. This psychological trick works because people naturally want to believe in sudden good fortune.

Golden rule: If it sounds too good to be true, it probably is.

Classic examples of “too good to be true” scams include:

➜ Emails claiming you have won a lottery you never entered
➜ Promises of a free vacation or luxury gift if you “just cover the shipping cost”
➜ Fake job offers with salaries far above industry standards
➜ Unrealistic discounts on popular products or services, often linked to shady websites

When faced with offers like these, it is always safer to step back and verify before clicking any links or sharing personal information.

7. Suspicious email addresses, hyperlinks, and domain names

Phishing emails are often sent from an address that is not consistent with the domain name or website of the organization that is being impersonated. For example, if you receive a message purporting to be from Microsoft but it was sent from an email address that ends in @gmail.com or @yahoo.com, then this should raise red flags for you.

It is also a good idea to check that the originating email addresses match previous correspondence. If there are hyperlinks in the email, hover over each one to see what URL it will take you to. If an email is supposedly from Amazon, but the hyperlink directs you to a different website entirely (like freeamazongifts.ca), that’s probably evidence of fraud.

8. Email coded entirely as a hyperlink

One deceptive tactic used by scammers is coding an entire email as a single hyperlink. This method is designed to trick users who have become cautious about clicking suspicious links inside an email. Instead of placing a visible link, fraudsters make the entire message clickable so that any click takes the recipient straight to a malicious website.

The most common way this attack is carried out is by sending an email that is not real text at all, but one large image designed to look like a normal email with text, buttons, and graphics. Since the whole image is wrapped in HTML code as a hyperlink, clicking anywhere in the message automatically redirects the user to a phishing or imposter page.

9. Unrealistic requests

Scammers often attempt to pressure people into breaking or bypassing normal company policies and security procedures. These requests are designed to feel urgent or confidential, making you act quickly without stopping to question them. Any demand that asks you to do something unusual or outside of standard processes is a major phishing indicator.

Red flag checklist:

➜ Requests to transfer money or approve payments outside of normal channels
➜ Instructions to share sensitive information like passwords, security codes, or employee data
➜ Pressure to bypass standard approval workflows “just this once”
➜ Demands to download unfamiliar software or open unusual file types

If an email urges you to take an action that feels out of step with your usual responsibilities, treat it as suspicious until verified through a trusted channel.
H3: 10. Emails with brief description

10. Emails with brief description

Not all phishing emails are long and detailed, but some short ones can fool you into thinking they’re legit. These kinds of short emails are usually brief and to the point—they often begin with “here’s your requested information” and then immediately attach malware files. For instance, scam artists will create spoofed emails from Peter of XYZ company that appear to be from a trusted vendor or supplier. These messages may include vague requests for information bundled with an attachment titled ‘additional information’ in hopes of luring the victim into clicking on it and compromising their computer’s security.

11. Unusual or generic greetings

Phishing emails often open with vague or generic greetings such as “Dear Customer,” “Valued Member,” or “Sir/Madam.” The lack of personalization is a red flag because legitimate businesses usually address you by name, especially if you already have an account with them.
Another warning sign is when the greeting feels culturally or contextually off. For example, an email from a local company that uses an overly formal or oddly worded introduction may indicate it is not genuine. Whenever you see a generic salutation that does not match your usual interactions with a business, treat the message with caution.

12. Fake URLs

A fake URL is one that looks like it belongs to a trusted brand but contains subtle differences. Attackers often register domains with misspellings, extra characters, or unusual endings to trick recipients into clicking. For example, they replace the letter “l” with the number “1”.

Scammers also take advantage of domain extensions, knowing that users may overlook whether a site ends in .com, .net, or another unfamiliar extension. In some cases, they even mix secure-looking links with insecure ones to create confusion.

To stay safe, always hover over links before clicking to inspect the real address. If you are unsure, type the official URL directly into your browser rather than trusting the link in the email.

How to Protect Yourself from Phishing

Phishing attacks continue to be one of the most common ways cybercriminals steal sensitive information. The best defense is staying alert and practicing safe online habits. By knowing what to look for and following a few key steps, you can greatly reduce the risk of falling victim to identity theft:

Verify sender identity – Always double-check the sender’s email address and confirm the source before clicking links or downloading attachments.
Enable multi-factor authentication (MFA) – Even if your password is stolen, MFA adds an extra layer of security that makes it harder for attackers to gain access.
Use email authentication protocols – Organizations should implement security measures like SPF, DKIM, and DMARC to help prevent spoofed emails from reaching inboxes.
Report suspicious emails – If something seems off, report it to your IT or security team instead of ignoring or deleting it.
Stay educated – Regular phishing awareness training keeps you and your team up to date on the latest tactics and how to respond safely.
