Understanding Email Spam Filters
Spam filters use complex algorithms to identify unwanted emails. While the exact rules vary by provider, certain words and patterns consistently trigger spam filters across Gmail, Outlook, and other major providers.
How Spam Filters Work
Modern spam filters look at multiple factors:
- Content analysis: Scanning for spam trigger words and phrases
- Sender reputation: Your domain and IP sending history
- Engagement signals: How recipients interact with your emails
- Technical factors: Authentication (SPF, DKIM, DMARC)
- Link analysis: Where your links point and their reputation
Categories of Spam Triggers
Urgency Words
Words that create false pressure: "Act now," "Limited time," "Urgent"
Financial Terms
Money-related triggers: "Free," "Cash," "Make money"
Overpromises
Too-good-to-be-true claims: "Guarantee," "Risk free," "100%"
Formatting Issues
Visual spam signals: ALL CAPS, excessive punctuation!!!
Best Practices for Avoiding Spam Filters
- Write naturally: If it sounds like spam, it probably is.
- Be specific: Generic phrases trigger filters; specific language doesn't.
- Avoid all caps: Even in subject lines, don't shout.
- Limit punctuation: One exclamation mark max, if any.
- Balance images and text: Image-heavy emails trigger filters.
- Use clear CTAs: Instead of "Click here," use descriptive links.
Spam filters look at the overall context of your email. A single trigger word probably won't send you to spam, but multiple triggers combined with poor sender reputation will. Focus on creating valuable, relevant content rather than obsessing over individual words.
