Plainer wording to try
- “urgent” → time-sensitive
- “free” → no-cost
- “act now” → when you have a minute
- “100% free” → no charge
- “limited time offer” → offer for this month
- “guaranteed” → expected
- “click here” → here is the link
- “deadline” → timeline
This checks wording only. Whether an email reaches the inbox depends far more on your domain's reputation, SPF, DKIM and DMARC, list quality and how recipients react.

113 phrases in five groups
The checker matches whole words and phrases, so “freelance” is not flagged as “free”. When two phrases overlap, the longer one wins, so “100% free” counts once. The groups are:
- Urgency and pressure: “act now”, “act immediately”, “urgent”, “limited time”, “limited time offer”, “expires today”, and more
- Money and pricing: “free”, “100% free”, “free money”, “free trial”, “free gift”, “cash”, and more
- Hype and over-promising: “guaranteed”, “guarantee”, “100% guaranteed”, “risk-free”, “no risk”, “amazing”, and more
- Phrases scammers use: “congratulations”, “you have been selected”, “you've been selected”, “winner”, “you won”, “prize”, and more
- Pushy calls to action: “click here”, “click below”, “click now”, “buy now”, “order now”, “call now”, and more
For many of them the tool suggests plainer wording. A cold email that sounds like one person writing to another tends to get more replies than one that sounds like an advert, whatever the filters make of it.
What matters more than words
Mailbox providers decide mainly on who is sending and how recipients respond. Set up SPF, DKIM and DMARC, ramp new mailboxes slowly with an email warmup schedule, and remove addresses that will bounce; the guide to verifying email addresses explains how. Then check the subject line with the subject line tester.
Spam words questions
Simply paste your cold email subject line and body copy into this free spam word checker. The tool instantly scans your text against over 250 common trigger phrases across urgency, finance, hype, and pushy sales patterns, highlighting potential deliverability risks without storing your copy.
Rarely on their own. Modern filters weigh the sender's reputation, authentication (SPF, DKIM and DMARC), bounce and complaint rates and how recipients react far more than individual words. Trigger phrases matter more as a sign of tone: an email full of them reads like a promotion to the person you are writing to, and that lowers replies.
It compares your text with a list of 113 phrases that deliverability guides commonly flag, grouped into urgency, money, hype, scam-like and pushy calls to action. It also counts all-caps words, exclamation marks and links. Everything runs in your browser and the text is not sent anywhere.
It is this tool's own rule of thumb: one point per trigger phrase, plus one point each for more than two all-caps words, more than one exclamation mark and more than two links. Up to one point is low, two to four is medium, five or more is high. Treat it as a prompt to reread the email, not a verdict.
No. A phrase in context is not the same as a phrase in a list. 'Free' in a sentence such as 'are you free on Thursday' is harmless to a reader, but the checker flags it anyway because it cannot judge meaning. Use the highlights to reread, then keep whatever reads naturally.
Authentication records on your domain, a gradual sending ramp for new mailboxes, and a list of addresses that exist. Bounces and complaints hurt deliverability far more than wording.
