Spam Word Checker
Paste your email below. This tool flags the patterns that genuinely hurt inbox placement — and shows you which “spam words” you can safely ignore.
Read this before you rewrite anything.
Spam filters stopped working from word lists years ago. Modern filtering at Gmail, Yahoo and Microsoft is machine learning trained on your authentication, your domain reputation, and how recipients reacted to your last emails. The word “free” from a sender with strong engagement lands in the inbox. The same word from a domain with a 0.4% complaint rate does not — and the word was never the reason.
What still hurts is patterns: shouting, deceptive promises, and emails built so a filter cannot read them. This tool checks for those, and it tells you when a flagged word is nothing to worry about.
Email Copy
Patterns worth fixing
Words we found, and why they're probably fine
What actually decides where this email lands
Copy is the smallest of the three factors that decide inbox placement. Check the other two:
- Scan your domain — MX, SPF and DMARC in one pass
- Count your SPF lookups — SPF fails silently above 10
- Check your blocklist status
