Spam Word Checker
Paste your email copy to flag spam-trigger words and get a quick spam-risk read before you send.
Check your copy for spam triggers
Certain words and patterns - aggressive sales language, money and urgency phrases, all-caps, excessive punctuation - raise the odds your email gets filtered. Paste your subject line and body and this tool flags the spam-trigger words it finds and gives a quick risk read.
Filters are far more sophisticated than a word list, so treat this as a first pass, not a guarantee. The biggest deliverability factors are still authentication and sending reputation - but clean copy helps. This runs entirely in your browser.
The patterns it flags
Filters react to categories of language and formatting, not just individual words. These are the usual culprits.
Money and urgency
Free, guarantee, act now, limited time, risk-free. Classic promotional triggers that feel out of place in a 1:1 email.
Shouting
ALL CAPS words, and excessive punctuation like !!! or $$$. Reads as a blast, not a personal note.
Hype and clickbait
Overblown claims and salesy superlatives that don't match a genuine outreach message.
Link and image heaviness
Lots of links, URL shorteners, or an image-only body - patterns filters associate with bulk marketing.
What actually keeps you out of spam
Keep it in perspective: word choice is a small factor next to authentication, sender reputation, and engagement. A perfectly-worded email from an unauthenticated, cold domain still lands in spam, while a plainly-written one from a warmed, authenticated domain reaches the inbox.
So treat this checker as the last 5 percent. Fix SPF, DKIM and DMARC, warm your mailboxes, and mail clean, well-targeted lists first. Then use clean, human copy - short, specific, minimal links - as the finishing touch rather than the strategy.
Frequently asked questions
Do spam-trigger words really matter?
They're a minor factor compared to authentication and sender reputation, but obvious spammy language (free money, act now, all-caps) does raise filtering odds. Clean copy is a cheap win.
Is this a guarantee my email won't hit spam?
No. Modern filters weigh reputation, engagement, authentication, and content together. A word check is a useful first pass, not a promise.
What matters more than spam words?
Authentication (SPF, DKIM, DMARC), sender reputation, warmup, and list quality all outweigh word choice. A clean-copy email from a bad-reputation domain still lands in spam; fix the fundamentals first.
Is my copy uploaded anywhere?
No. The spam checker runs entirely in your browser.
