In today’s digital age, our inboxes are constantly flooded with emails. While many of these emails are legitimate and important, there’s also a considerable amount of spam that manages to sneak its way into our inboxes.

Spam emails not only clutter our email folders but also pose security risks. It’s crucial to know how to identify and filter out spam emails effectively. In this guide, we’ll teach you how to check if an email is spam and provide useful tips to keep your inbox clean and secure.

1. Check the Sender’s Email Address

One of the simplest ways to spot a spam email is to examine the sender’s email address. Legitimate organizations and individuals usually have professional and recognizable email addresses. Be wary of email addresses that contain random strings of characters or look suspicious. Also, pay attention to misspellings or slight variations of well-known domain names (e.g., instead of These are common tactics that spammers use to deceive recipients.

2. Look for Generic Greetings

Spam emails often begin with generic greetings like “Dear Customer” or “Hello User” instead of addressing you by your name. Legitimate organizations that have your contact information should use your name in their emails. If the email lacks personalization or uses an incorrect name, it’s a red flag.

3. Check for Spelling and Grammar Errors

Many spam emails originate from non-English-speaking countries and are hastily composed. As a result, they often contain noticeable spelling and grammar mistakes. If an email is riddled with errors or awkward language, it’s likely spam.

4. Beware of Urgent or Threatening Language

Spammers often use fear tactics to prompt quick action. Be cautious of emails that claim your account will be suspended, your data will be deleted, or you’ll face legal consequences unless you act immediately. Legitimate organizations usually provide clear and concise information without resorting to intimidation.

5. Verify Hyperlinks and URLs

Hover your mouse pointer over any hyperlinks in the email without clicking them. A tooltip should appear, showing the actual URL where the link will take you. If the URL doesn’t match the sender’s domain or looks suspicious, it’s a strong indication of a phishing attempt. Never click on such links.

6. Check for Attachments

Spam emails may contain malicious attachments, such as infected files or links to download harmful software. Unless you were expecting an attachment from the sender, be cautious about downloading or opening any files.

7. Inspect the Email’s Header

Email headers contain technical information about the email’s origin. While it might look complex, examining the header can provide valuable information. You can usually access the email header in your email client settings. Look for inconsistencies or suspicious server information.

8. Avoid Sharing Personal Information

Legitimate organizations won’t ask you to share sensitive information (like passwords or credit card details) via email. Be skeptical of any email requesting such data. If you have doubts, contact the organization directly through their official website or phone number rather than using the contact information provided in the email.

9. Use Spam Filters

Most email services and clients come equipped with spam filters. Make sure yours is activated and regularly updated. These filters use algorithms and blacklists to automatically flag and move suspected spam emails to a dedicated folder, keeping your inbox cleaner and safer.

10. Trust Your Instincts

If an email feels off or too good to be true, trust your instincts. Spam emails often try to exploit emotions like curiosity, fear, or excitement. When in doubt, don’t hesitate to delete the email or mark it as spam.
