FAQ

Questions about spam word checker

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.

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.

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.

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.

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

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

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.
