Email Spam Word Checker
Paste your subject and body to catch the spam-trigger words and phrases that can drag down deliverability — with a quick risk score and a list of exactly what to soften before you send.
Trigger words are a symptom, not the disease
It's worth being honest about how much word choice actually matters, because the internet is full of overblown "spam word" lists that treat the filter like a 1998 keyword scanner. Today's filters are machine-learned and lean heavily on whether you're authenticated, whether you have a sending history, and whether real people open and reply to your mail. A clean, opted-in list will reach the inbox even with the odd "free" in the copy. That said, language that reads like a scam tends to come bundled with everything else that hurts you — so if your draft is wall-to-wall urgency and exclamation marks, the words are usually the visible tip of a deeper relevance problem worth fixing.
Write like a person emailing a person
The most reliable way to dodge spam phrasing is simply to write the way you'd write to one specific customer you respect. You wouldn't scream "ACT NOW!!!" at a friend, promise them risk-free guaranteed riches, or hide your real intent behind "click here." Plain, specific, honest copy clears filters and converts better, because it builds the trust that urgency theatre destroys. Use this checker to catch the reflexes that creep in when we put on a "marketing voice," then rewrite those lines in your normal one. The inbox rewards mail that sounds like it came from a human who actually has something useful to say.

Frequently asked questions
Do spam-trigger words still matter?
Modern spam filters rely far more on sender reputation, authentication (SPF, DKIM, DMARC) and engagement than on a keyword blocklist. But trigger words still matter at the margin: a subject stuffed with 'FREE!!! ACT NOW' combined with weak reputation tips you over the edge. Treat this checker as a copy-quality nudge, not a deliverability guarantee.
What actually lands email in spam?
The biggest factors are authentication and reputation: are you who you say you are, and do people who get your mail engage with it. Sending to people who didn't opt in, high complaint rates, and poor list hygiene do more damage than any single word. Fix those first, then clean up obviously spammy phrasing.
How do I improve deliverability beyond word choice?
Authenticate your domain with SPF, DKIM and DMARC; only email people who opted in; remove inactive subscribers; keep a consistent sending volume; and make unsubscribing easy. A clean, engaged list with good authentication will reach the inbox even with imperfect copy.
