## What are spam trigger words?

Phrases that show up often in promotions and scams, such as act now, guaranteed or 100% free. Filters look at the whole message, so one word rarely sinks an email, but several together make it read like a promotion.

## Will removing these words keep me out of spam?

Not on their own. Mail filters weigh your sending domain, its setup and reputation, how many people reply, and the content. This checker covers the content part only.

## Where does the word list come from?

It is a hand-picked list of phrases that cold email guides and filter rule sets flag again and again. No mail provider publishes its filter, so no list is complete.

## Why does it count links and capitals?

A short email with many links or words in capitals reads like a newsletter or an ad. The checker flags more than 2 links, words of 4 or more capital letters and more than 1 exclamation mark.

## Is this spam word checker free?

Yes. It runs in your browser, needs no account and has no limit. Nothing you paste is sent anywhere.

## Does it check my sending domain?

No. It reads only the text you paste. Domain setup such as SPF, DKIM and DMARC needs a separate check.

## Can it rewrite the email for me?

No, it shows a suggestion next to each hit and you edit. The cold email generator on this site writes drafts and runs this same check on them.
