What does a SpamAssassin 'try it' message from mail-tester.com mean?

Summary

A SpamAssassin 'try it' message from mail-tester.com indicates that a URL within your email has triggered the URI_TRY_3LD rule or similar rules designed to identify potentially suspicious URLs based on patterns commonly found in spam. This doesn't necessarily mean the literal phrase 'try it' is present. The URI_TRY_3LD rule flags URLs that contain 'try', 'start', 'get', etc., in the hostname's third-level domain. SpamAssassin assigns a score to different email characteristics, and these flags contribute to the overall score. While it can affect inbox placement, a single flag doesn't guarantee your email will go to spam; it's one factor among many and can sometimes be a false positive. Email providers can customize SpamAssassin configurations, affecting the impact of specific rules. Therefore, focus on deliverability best practices: legitimate URLs, proper authentication (SPF, DKIM, DMARC), list hygiene, engaging content, and building a good sender reputation, rather than obsessing over specific trigger words.

Key findings

  • URI_TRY_3LD Trigger: 'Try it' message likely means a URL triggered SpamAssassin's URI_TRY_3LD rule due to keywords in the third-level domain.
  • Pattern Matching: SpamAssassin identifies spam through patterns, not necessarily exact phrases.
  • Score Contribution: 'Try it' flag contributes to an email's overall SpamAssassin score.
  • Not a Guarantee of Spam: A single SpamAssassin flag does not guarantee an email will land in the spam folder.
  • Customizable Configurations: SpamAssassin configurations can be customized by email providers, affecting rule impact.
  • Best Practices Matter More: Focusing on best practices (authentication, list hygiene, content) is more effective than avoiding specific words.

Key considerations

  • Review URLs: Carefully review all URLs in your email for suspicious patterns or keywords.
  • Authentication: Ensure SPF, DKIM, and DMARC are correctly configured to improve deliverability.
  • Sender Reputation: Build and maintain a positive sender reputation through consistent, responsible sending practices.
  • Content Quality: Create engaging and valuable content to minimize spam complaints.
  • Testing: Use tools like mail-tester.com to test your email's SpamAssassin score before sending.
  • Perspective: Don't overreact to a single 'try it' flag; consider the overall context and quality of your email.
