What is Spam Checker?
Spam Checker is a free tool that analyzes suspicious emails to determine if they're spam, phishing, or legitimate. Every day, millions of spam emails are sent worldwide, containing phishing attempts, malware, scams, and unwanted advertisements. This tool helps you identify dangerous emails before they cause harm.
Simply paste the complete email content (including raw SMTP headers) into the tool, and within seconds you'll get a spam score, detailed analysis, and a clear verdict.
Understanding Your Results
The Spam Score is a number that indicates how suspicious the email is based on standard anti-spam filters:
Score below 5.0 (Ham)
The email is considered legitimate (ham). Lower scores indicate trustworthy routing. You can generally interact with it safely.
Score 5.0 or above (Spam)
The email exhibits spam characteristics. Do not click any links, do not download attachments, and delete the email immediately.
When to Use Spam Checker
Check emails with links you don't recognize or that seem unusual.
Verify emails from senders you don't know or trust.
Check emails asking for money, account details, or cryptocurrency.
Verify emails claiming urgent action or account suspension is required.
Stop Wasting Time on Spam
Analyzing spam is good, but preventing it is better. Stop giving out your real email address. Use temp mail instead of real accounts and you'll never have to worry about spam again.

How do I get email headers?
In Gmail, open the email, click the three dots next to Reply, and select "Show original". In Outlook, double-click the message, go to File > Properties, and find "Internet headers". Copy all that text.
How private is my data?
Unlike other tools that send your email to an external server for analysis, our tool runs the scoring algorithm directly in your local browser using JavaScript. We never store, log, or transmit your emails.
What does the spam score mean?
It is an aggregated threat metric. A score below 5.0 generally means the email is safe (Ham). A score of 5.0 or higher triggers spam filters. Scores above 7.0 usually indicate malicious intent, spoofing, or phishing.
What is the difference between Spam and Phishing?
Spam is generally unwanted bulk email (like aggressive marketing or junk mail) that is annoying but usually harmless. Phishing, however, is a malicious cyber attack where the sender pretends to be a trusted entity (like your bank or PayPal) to steal your passwords or credit card numbers. Our tool detects technical signatures of both.
Why did a legitimate email get a high spam score?
This is known as a "false positive." It usually happens when a legitimate company misconfigures their email server (e.g., broken SPF or DKIM records), uses spam-like trigger words in their subject line, or sends emails through a shared server with a bad reputation. The score reflects the technical risk, not the sender's intent.
What should I do if I clicked a link in a spam email?
First, disconnect from the internet to prevent potential malware from communicating with its server. Run a full system scan with reputable antivirus software. If you entered any passwords on the linked site, immediately change those passwords on the real websites. To avoid this, always analyze suspicious emails here before interacting.
