Email Spam Checker Tool

Our tool analyzes your email content against a database of known spam trigger words and phrases. Each word is assigned a point value based on its spam impact level (1-4 points). The tool calculates your total spam score by adding up all the points from detected spam words. The higher your score, the more likely your email is to be flagged as spam.

• 0-5 points (Green – Low Risk): Your email looks good! It has minimal spam triggers and is unlikely to be marked as spam.
• 6-15 points (Orange – Medium Risk): Your email has some spam triggers. Consider revising to improve deliverability.
• 16+ points (Red – High Risk): Your email is likely to be marked as spam. Significant changes are recommended.

We categorize spam words into four impact levels:

🚨 High Impact (4 points each): Severe spam triggers like pharmaceutical terms (viagra, pills), adult content, get-rich-quick schemes, fake lottery wins, and miracle cures.

⚠️ Medium-High Impact (3 points each): Aggressive marketing language like “100% free,” “act now,” “click here,” “limited time,” and “risk-free.”

⚡ Medium Impact (2 points each): Common promotional words like “guarantee,” “amazing,” “opportunity,” “save money,” and “proven results.”

💡 Low Impact (1 point each): Mild marketing terms like “best,” “new,” “special,” “professional,” and “online.”

While our tool provides valuable guidance, it’s not a guarantee. Different email providers use different spam filters with varying algorithms. Our tool checks for common spam triggers, but factors like sender reputation, email authentication (SPF, DKIM), and recipient engagement also affect deliverability.

• Sender reputation and domain authority
• Email authentication (SPF, DKIM, DMARC records)
• Email list quality and engagement rates
• Sending frequency and volume
• HTML-to-text ratio in your email
• Number and quality of links in your email
• Image-to-text ratio
• Subject line content

• Remove high-impact words: Eliminate pharmaceutical terms, adult content references, and get-rich-quick language.
• Use natural language: Write like you’re talking to a friend, not selling to a stranger.
• Avoid excessive punctuation: Don’t use multiple exclamation marks or ALL CAPS.
• Be specific: Use concrete details instead of vague promises.
• Personalize content: Use the recipient’s name and relevant information.
• Include an unsubscribe link: This is legally required for marketing emails.
• Balance images and text: Don’t use image-only emails.

No, content is just one factor. Modern spam filters also consider sender reputation and IP address history, domain age and authentication, recipient engagement (opens, clicks, replies), complaint rates and unsubscribe rates, sending patterns and volume, and technical factors like proper HTML formatting.

The total word count helps you understand your email length. Very short emails (under 50 words) or emails with a poor text-to-link ratio can trigger spam filters. Aim for meaningful content with a good balance of text.

Yes, sometimes spam trigger words are necessary for legitimate content. If you must use them:

• Use them sparingly and in proper context.
• Balance them with quality, natural content.
• Ensure your overall score stays low.
• Focus on other deliverability factors like authentication and sender reputation.

No, our SPAM Checker tool runs entirely in your browser. Your email content is not sent to any server, stored, or shared with anyone. All processing happens locally on your device for complete privacy.

You can check your subject lines with our Spam Checker tool too! Simply paste your subject line into the content area. Subject lines are especially important as they’re often the first thing spam filters analyze. Keep them under 50 characters and avoid excessive punctuation or all caps.

Check every marketing or promotional email before sending. For transactional emails (order confirmations, password resets), check your templates once and then periodically if you make changes. Regular newsletters should be checked each time, as content varies.

Some legitimate businesses (pharmacies, financial services, weight loss clinics) naturally use words that trigger spam filters. In these cases:

• Focus heavily on domain authentication and sender reputation.
• Build trust through consistent, permission-based sending.
• Use very specific, factual language rather than promotional hype.
• Include clear business identification and physical address.
• Consider using subdomain or dedicated IPs for transactional vs. marketing emails.

Yes, different industries have different challenges:

• E-commerce: Avoid overusing “sale,” “discount,” “limited time”.
• Finance: Be careful with “investment,” “guaranteed returns,” “risk-free”.
• Health/Wellness: Avoid “miracle,” “cure,” “lose weight fast”.
• B2B: Minimize “free consultation,” “limited spots,” “act now”.
• Education: Be cautious with “certification,” “guaranteed results,” “easy”.

Yes, but keep in mind that spam filters analyze the actual content you send. Always test with real content that represents what you’ll actually send. Dummy content might give you a false sense of security if it’s very different from your real emails.
