Campaign Cleaner's AI-powered Spam Keyword tool scans every word in your email, flags high-risk triggers, and gives you a clear keyword ratio so you know exactly what to fix before your campaign goes out.
Quick Overview of Features
Spam trigger words are terms and phrases that spam filters flag as indicators of unsolicited or deceptive email. They range from overt financial urgency language - "guaranteed," "risk-free," "earn money" - to promotional superlatives, pressure tactics, and adult content terms. While no single word is guaranteed to send your email to spam, a high density of trigger words combined with a weak sender reputation is one of the most reliable ways to fail content filtering.
The spam keyword ratio measures what percentage of the words in your email are recognized spam triggers. Campaign Cleaner calculates this ratio and flags anything above 5% as high risk. Even at lower ratios, certain high-weight keywords - particularly those associated with pharmaceutical spam or financial scams - carry outsized filter penalties regardless of their frequency in the text.
Spam filters group trigger words into risk categories. Financial urgency language ranks highest: "guaranteed," "no risk," "earn money fast," "cash bonus," "double your income." Promotional pressure terms follow: "act now," "limited time offer," "don't delete," "special promotion," "urgent." Superlative claims like "best price," "lowest rate," and "amazing deal" also score heavily. Opt-out manipulation ("you have been selected," "you are a winner," "claim your prize") and formatting signals like ALL CAPS words, excessive exclamation marks, and stacked currency symbols also carry significant filter weight.
Yes - though modern spam filters are more contextual than they were a decade ago. Today's filters combine content analysis with sender reputation, authentication signals, engagement history, and HTML quality. A sender with strong DMARC alignment and high open rates can use the word "free" without issue. A new sender with no authentication history and a keyword-dense email will almost certainly land in spam. Campaign Cleaner addresses the content layer so your emails are clean before the reputation layer is even tested.
Improving your keyword ratio is mostly about substitution and tone. Replace urgency language with specific, factual statements - "offer ends Friday" instead of "act now." Avoid superlatives unless backed by verifiable data. Remove ALL CAPS emphasis and replace with bold formatting or sentence structure. Cut promotional preamble from subject lines - "FREE GIFT INSIDE" is one of the most reliably flagged patterns. Run every campaign through Campaign Cleaner before sending to catch high-risk terms you may have missed in editing.
