Email Spam Words Checker
This email spam words checker scans your subject line and body for the trigger words and phrases that mailbox filters watch for. Paste your draft, click Analyze, and you get a 0–100 spam score plus a list of exactly which words could push your message into the spam folder.
It is built for anyone who needs their email to actually land in the inbox — marketers writing campaigns, sales reps sending cold outreach, support teams, and newsletter writers. Instead of guessing why emails go to spam, you can spot the risky words and rewrite them before you hit send.
How to Check Your Email for Spam Words
Enter your email content
Type or paste your subject line into the Email Subject field and your message into the Email Body area. You can check the subject only, the body only, or both together.
Analyze
Click Analyze, or press Enter in the subject field or Ctrl+Enter in the body. The tool scans your text against a database of known spam trigger words.
Review your score and findings
See your spam score with a risk level, a per-category breakdown of the words found, and a Highlighted Preview that flags every detected word right in your text.
Revise and re-check
Remove or reword the highlighted words, then Analyze again to watch your score drop. Aim for a score below 20 for the best deliverability.

Frequently Asked Questions
What are email spam trigger words?
Spam trigger words are words and phrases that appear so often in junk mail that filters treat them as warning signs — things like "act now", "free money", "guaranteed", or "risk free". One or two are usually fine, but stacking several of them raises the odds your email is flagged. This tool detects them and groups them into six categories so you can see which signals your draft is sending.
How do I check my email for spam words?
Paste your subject line and body into the fields above and click Analyze. You will get a spam score from 0 to 100, a category breakdown of every trigger word found, and a Highlighted Preview that marks each word in your text. Reword the highlighted phrases and re-run the check to confirm your score improved.
What is a good spam score?
A score of 0–20 is considered safe and unlikely to trip spam filters. Scores of 21–45 are medium risk — worth revising a few words. Anything above 45 is high risk and has a strong chance of being filtered. The score is weighted: each detected word carries a severity from 1 (low) to 5 (very high), so a single mild word barely moves the needle while several strong ones add up fast.
Why do my emails go to the spam folder?
Content is one common reason: too many trigger words, ALL CAPS subjects, excessive exclamation marks, or fake Re:/Fwd: prefixes all look spammy to filters. This tool focuses on those content signals. Be aware that mailbox providers also weigh factors outside the message text, which the next answer covers.
Does removing spam words guarantee inbox delivery?
No. Cleaning up trigger words clearly helps, but providers like Gmail and Outlook also consider sender reputation, email authentication (SPF, DKIM, DMARC), sending patterns, and how recipients engage with your mail. This checker improves the content side of deliverability; it cannot control those other factors.
Why are common words like "free" or "discount" flagged?
These words are not bad on their own, but they show up constantly in spam, so filters watch for them. Because the scoring is weighted, a single "discount" (weight 2) adds only a little, while the risk grows when many trigger words are combined. Focus on the high-weight words shown first in each category for the biggest improvement.
Does this tool work for non-English emails?
Yes. It ships with spam word databases for English, Vietnamese, Chinese (Simplified), Spanish, Portuguese (Brazil), and Indonesian, and automatically loads the one matching your current language, with English as a fallback.
Is my email content stored or sent anywhere?
No. All analysis happens in your browser with JavaScript. Your subject line and body are never uploaded to a server and nothing is stored or tracked, so your draft stays completely private.
