Spam-word checkers are 2010 thinking
Tools like Mail-Tester and various 'spam score' scanners still flag words like 'free' and 'guarantee'. Modern filters barely care about vocabulary.
What actually triggers filters now
— Sending reputation (IP + domain history) — the dominant factor
— Engagement signals (replies, marks-as-read vs deleted-unread)
— Authentication pass (SPF/DKIM/DMARC alignment)
— Link/image density and tracking domains
Mail-Tester
— Pros: genuinely useful for auth + blacklist + content structure in one score
— Cons: the 'spam words' component is mostly noise; people fixate on it
The better use: run Mail-Tester to confirm auth passes and you're not blacklisted — ignore the word-level nags. A clean plain-text email with the word 'free' from a warmed, authenticated domain inboxes fine. A 'free'-free email from a cold IP doesn't.
Verdict: 4/5 Mail-Tester for auth/blacklist, 1/5 for its spam-word advice.
Who it's for: senders rewriting copy to dodge 'spam words' instead of fixing reputation.
