About spam trigger words

Spam filters look at many signals, not just keywords. However, certain words and patterns can increase spam scoring, especially for new senders or when combined.

Other factors that matter:

  • Sender reputation - Most important factor
  • Email authentication - SPF, DKIM, DMARC
  • Engagement rates - Opens, clicks, replies
  • Spam complaints - Keep under 0.1%
  • List quality - Avoid purchased lists

About this tool

Spam filters look at many signals, and content is just one of them. While this checker identifies high-risk words, remember that your sender reputation is the primary factor. Build trust by maintaining proper SPF, DKIM, and DMARC authentication and keeping your list clean with our email validator. Monitor your sender reputation using our blacklist checker, and track your bounce rates with the campaign calculator to catch problems early.

Yes, in moderation and with good sender reputation. One 'free' in a legitimate offer is fine. Multiple trigger words combined with poor engagement signals is problematic. Focus on building reputation first.

Major factors: sender reputation (most important), authentication (SPF, DKIM, DMARC), engagement rates, spam complaint rates, list quality, and sending patterns. Content is important but not the only factor.
