What is Spam Checker?

Spam Checker is a free tool that analyzes suspicious emails to determine if they're spam 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 headers) into the tool, and within seconds you'll get a spam score, detailed analysis, and a clear verdict: spam or ham (legitimate email).

How to Get Email Headers

To check an email for spam, you need the copied email including headers. Headers contain important information like sender details, IP addresses, and routing information that help identify spam. Here's how to get them from popular email clients:

Understanding Your Results

The spam score is a number that indicates how suspicious the email is:

Score below 5: The email is considered legitimate (ham). Lower scores (closer to 0) indicate more trustworthy emails.

Score 5 or above: The email is considered spam. Higher scores indicate more suspicious content. Be very cautious with emails scoring 10 or higher.

Below you can see the rules that were triggered and what they checked (e.g., HTML_MESSAGE, DKIM_INVALID). Read description to understand why the rule triggered and what it detected.

💀 If the email is spam

Don't click any links or download attachments
Don't reply to the email
Mark it as spam in your email client
Delete the email

✅ If the email is legitimate, you can interact with the email.

However, always check the sender and the content if you're unsure. Be cautious if someone asks for your personal information.
