What is an Email Spam Score?
An email spam score is a metric generated by spam filters (like SpamAssassin) that evaluates the likelihood of your email being classified as spam. The filter analyzes your email's headers, HTML structure, text-to-image ratio, and specific keywords to assign a score. The higher the score, the more likely the email will be blocked.
Factors That Increase Your Spam Score
- Spammy Keywords: Excessive use of words like "Free", "Guarantee", "Click Here", or ALL CAPS in the subject line.
- Broken Authentication: Failing SPF or DKIM checks immediately raises your spam score.
- Text-to-Image Ratio: Sending an email that is just one large image with no text is a classic spammer tactic and will be heavily penalized.
- HTML Errors: Broken HTML tags, empty links, or messy code generated by Microsoft Word can trigger filters.
How to Lower Your Spam Score
Run your email copy through our Spam Score Checker before sending. Ensure your HTML is clean and responsive, maintain a healthy balance of text and images, avoid link shorteners (which spammers use to hide malicious URLs), and authenticate your sending domain.
Frequently Asked Questions
What does the Spam Score Checker tool check?
The Spam Score Checker tool analyzes your email content, domain configuration, and sending infrastructure for factors that affect whether emails reach the inbox or land in spam. It checks against rules used by major spam filters and email providers including Gmail, Outlook, and Yahoo. The tool identifies specific issues — such as missing authentication, spam trigger words, poor text-to-image ratio, or missing unsubscribe links — and explains how to fix them.
What are the most common causes of emails going to spam?
The most common causes of emails landing in spam are: (1) Missing or failing SPF, DKIM, or DMARC authentication. (2) Sending from a new IP or domain without a warm-up period. (3) High bounce rates or spam complaint rates (above 0.1% triggers filters). (4) Spam trigger words in subject lines or body. (5) No unsubscribe link in bulk email. (6) Poor text-to-image ratio (image-heavy emails are suspect). (7) Domain or IP on blacklists. Fix these issues systematically using our free deliverability tools.
What is a good email spam score?
Most spam filter scoring systems (including SpamAssassin, which our Spam Score Checker is based on) consider a score below 2.0 to be acceptable. Scores between 2.0 and 5.0 indicate potential issues that should be investigated. Scores above 5.0 significantly increase the likelihood of spam classification. Common score contributors include missing authentication records, spam trigger words, all-image emails, shortened URLs, and excessive punctuation in subject lines.
How do I improve my email inbox placement rate?
To improve inbox placement: (1) Set up SPF, DKIM, and DMARC correctly. (2) Warm up new IPs gradually — start with small volumes and increase over weeks. (3) Keep bounce rates below 2% and spam complaint rates below 0.1%. (4) Send only to engaged subscribers — segment and suppress inactive users. (5) Use double opt-in to ensure valid, consenting recipients. (6) Include a working unsubscribe link. (7) Monitor your sender reputation and blacklist status regularly.
