Stop wondering if your emails will reach the inbox. Our free tool analyzes your email's spam score, authentication, and content to ensure maximum deliverability.
We verify your email's setup to ensure it meets modern security standards. This includes checking your SPF records to validate sending servers, DKIM signatures to confirm email integrity, and DMARC policies to prevent email spoofing. Proper authentication significantly improves delivery rates and protects your domain reputation.
Your sending IP's reputation is checked against major reputation databases and email provider feedback loops. We analyze historical sending patterns, complaint rates, and blacklist status. This helps identify if your sending infrastructure might be flagged by email providers, allowing you to address issues before they affect deliverability.
We scan your domain and IP against 20+ global blocklists including Spamhaus, Abusix, and Spamcop. If your domain appears on any blocklist, we provide detailed information about the listing reason and step-by-step instructions for getting delisted. Regular monitoring helps catch blocklist issues early.
We run your email through SpamAssassin, the industry's leading spam detection system. This comprehensive check analyzes over 500 criteria to generate a spam probability score. Lower scores (below 2.0) indicate better deliverability, while higher scores may trigger spam filters. Each rule violation is clearly explained with actionable fixes.
Our advanced content scanner identifies potential spam triggers in your subject line and email body. We check for problematic phrases, excessive punctuation, and other content patterns that commonly trigger spam filters. The analysis includes specific recommendations for rewording while maintaining your message's effectiveness.
Every link in your email undergoes a multiple security checks. We verify domain reputation, SSL certificates, and redirect chains. The analysis flags potentially problematic links, including those to domains with poor reputation or suspicious patterns. This helps prevent your email from being blocked due to harmful or suspicious links.
How accurate are the test results?
Our tool uses real-world spam filtering criteria and updated databases to provide accurate results. While each email provider has unique spam filtering rules, our analysis covers the most common factors affecting deliverability across major providers like Gmail, Outlook, and Yahoo.
What spam score is considered good?
A SpamAssassin score below 2.0 is considered good and indicates a high likelihood of inbox delivery. Scores between 2.0 and 5.0 may trigger spam filters, while scores above 5.0 are likely to be marked as spam. Our report includes specific recommendations to improve your score.
