Email mini app
Cold Email Spam Word Checker
Spam-word checkers help you notice language that can sound overly promotional, but no single word determines deliverability.
Free · no API requiredWhat this free checker helps you do
Paste a subject line and email body to find potentially risky sales language. This checker runs entirely in the browser and uses a transparent local phrase list.
How to use it
- 1
Paste the subject line and the email body you plan to send.
- 2
Review flagged terms in context instead of deleting them automatically.
- 3
Replace hype with a specific, verifiable claim or question.
What the checker looks for
The checker scans a local list of promotional, urgency, and money-related phrases. It assigns a directional risk level from the number and severity of matches; inbox providers use their own rules.
Useful guardrails
- Avoid unnecessary urgency and exaggerated outcomes.
- Use plain language that matches the proof you can offer.
- Keep authentication and list hygiene separate from copy review.
Questions people ask
About this mini app
Can one word send a cold email to spam?
Usually not by itself. Deliverability depends on sender reputation, authentication, recipient engagement, list quality, and the complete message.
Should I remove every flagged word?
No. Review why it was flagged and replace only language that is vague, promotional, or unnecessary.
Does this checker send my email anywhere?
No. The analysis uses local code in the browser and makes no API request.
