Detected Spam Words
Paste your email copy into the email spam checker above. It highlights spam trigger words as you type, sorts them into five categories and gives you a spam score, word count and read time.
How to check your email for spam words
Run every new template through the spam word checker before it goes into a sequence.
- 1
Paste the full email
Include the subject line and the body. Filters read both, and subject lines carry extra weight.
- 2
Review the highlights
Each flagged word is colored by category, so you can see whether the problem is urgency, sales language or money talk.
- 3
Rewrite the flagged phrases
Swap pushy wording for plain, specific language. Edit in place and watch the spam score drop.
- 4
Save the report
Email the report to yourself or a teammate so the clean version is the one that gets loaded.

Scam and shady

Guaranteed, 100% free, risk-free, double your sales, miracle results.
What reads clean
A specific reason for writing, a short question and a plain sign-off.
Before and after: fixing spam words in a cold email
Most spammy cold emails are written to sound exciting. The fix is to sound like a person writing to one other person.
Cut the claims, name the reason you are writing, and ask one small question. Shorter emails also tend to score better because there is less room for trigger words.
- Keep cold emails under about 120 words
- Use one link at most, and no attachments
- Avoid all caps and repeated punctuation
- Personalize the first line so templates vary
What an email spam checker cannot tell you
Copy is one input. Gmail, Outlook and Yahoo also look at your sending domain, your authentication records, your bounce rate and how recipients react to your mail.
A clean email from a domain with no DKIM or DMARC can still land in spam. Since February 2024, Gmail and Yahoo require SPF, DKIM and DMARC from anyone sending more than 5,000 messages a day. Run the domain scanner to check your setup before you blame the words.
Yes. Paste as many emails as you like, with no signup. You can email the report to yourself to keep a record of the clean version.
Spam trigger words are phrases that spam filters and readers link with junk mail, such as "act now", "guaranteed" or "free money". One word rarely sinks an email, but several together raise your score.
Lower is better. Aim to keep the score low and the flagged words few, especially in the subject line. If a word is essential to your offer, keep it and make the rest of the email plain.
No. Copy is only part of the picture. Authentication, domain age, sending volume, bounces and engagement all affect placement. Pair this checker with a domain health check.
Yes. Paste the subject line with the body. Subject lines are short, so a single trigger word there stands out more than one buried in a paragraph.
