Detect and remove spam keyword triggers before you send - and keep your ratio below the 5% threshold for optimal deliverability.
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.

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. Practical steps include:
