Email Spam Checker

This email spam checker scores a subject line and message body from 0 to 10 against transparent content rules: spam trigger words, all-caps text, exclamation marks, link count, URL shorteners, image-only HTML and missing unsubscribe wording. Each flagged rule says why it was flagged. It does not test sender reputation, blacklists or inbox placement.

How to Use the Email Spam Checker

To check an email for spam words and other content triggers, paste the message, run the check and fix what is flagged.

  1. Enter the subject line and paste the message body as plain text or HTML.
  2. Select Check spam score to run the content rules locally in your browser.
  3. Read the score out of 10 and the explanation next to every flagged rule.
  4. Edit the flagged wording, links or images and check the message again.

How the Email Spam Score Is Calculated

The email spam score adds points for seven content rules, and the total is capped at 10, so you can see exactly where every point comes from.

Email Spam Words Checker

The subject and body are searched for common trigger phrases such as act now, risk free, click here, limited time and 100% free. Each phrase found adds one point, up to three points, and the result lists the phrases. One phrase is rarely a problem in itself, but several together make a message read like bulk promotion.

Spam Triggers in Formatting and Links

More than half of the letters in capitals adds two points, and three or more exclamation marks add one. More than five links, or a link through a shortener such as bit.ly, adds a point each. HTML with images and fewer than 30 characters of readable text adds two points.

Unsubscribe Wording and Spam Content

A body without the words unsubscribe, opt out or manage preferences adds one point. The rule matters mainly for newsletters and marketing mail, where a clear way to opt out is expected. A score of 0 to 2 is low, 3 to 5 deserves review and 6 or more is high.

Email Spam vs Phishing

Spam is unwanted bulk mail, while phishing is a deceptive message built to steal information, and a content score can miss either one.

Frequently Asked Questions

What Is an Email Spam Checker?

An email spam checker reviews a message for patterns that spam filters and readers tend to distrust. This one checks the content only, with rules you can read, and does not copy any mailbox provider’s filter.

Why Do Legitimate Emails Go to Spam?

Missing SPF, DKIM or DMARC records, a sender or IP address with poor reputation, low engagement and promotional wording can each push mail into spam. Content is only one of these factors, so check your DNS records as well as the message.

Will My Email Go to Spam?

No content test can promise inbox placement, because each provider decides with its own signals. A low score here means the text has few known red flags; sending a test message to your own inboxes shows where it really lands.

Can It Check an Email Address for Spam?

No. The checker reads message content, not sender addresses or domains. Use the Email Blacklist Check for a domain or IP address, and the Scam Email Checker for a suspicious message you received.
