Email Spam Word Checker

Land in the inbox, not the spam folder. Paste your email and this flags the spam-trigger phrases, ALL-CAPS and punctuation that filters dislike — so you can clean it up before sending.

Need more than the free basics? Wording is one deliverability factor; your sending infrastructure is another. A proper email-sending service like SMTP2GO handles authentication, reputation and inbox placement.

Spam words are only part of deliverability

Trigger phrases, shouty caps and exclamation pile-ups raise your spam risk — but modern filters weigh many signals: your domain authentication (SPF, DKIM, DMARC), sender reputation, engagement and list hygiene. Clean copy helps, yet if your infrastructure isn't set up right, even a perfect email can hit spam. Fix both: tidy the words here, and send through an authenticated service.

Frequently asked questions

Do spam-trigger words really matter?

They contribute to your spam score. Words like 'free', 'act now' and '$$$', plus heavy caps and exclamation marks, raise the risk — but they're one factor among many.

What else affects deliverability?

Domain authentication (SPF/DKIM/DMARC), sender reputation, list quality and engagement. A proper sending service like SMTP2GO handles the technical side.

Does this scan my actual deliverability?

No — it checks your wording locally. Real inbox placement depends on your sending setup, which an authenticated provider manages.
