Email spam checker for cold email.
Paste your subject and body. Spam words and risky formatting light up as you type, and a free deep check predicts the folder and marks the sentences to cut or rewrite.
Two checks, one page.
The word and format scan runs in your browser on every keystroke. It looks for about 180 phrases in seven groups (false urgency, money talk, hype, pushy calls to action, scam language, marketing-blast wording and the cold email cliches readers skim past) and for the formatting filters react to: words in capitals, exclamation marks, more than one link, link shorteners, prices and percentages, and a fake Re: in the subject. Merge tags like {{first_name}} are ignored.
The deep check reads the email as a whole, the way a filter and a busy reader would. It predicts the folder (primary, promotions or spam) with a confidence, gives an inbox score from 0 to 100, names the problems with the email as a whole (reads like a pitch, generic opener, no clear ask, too long), and marks each sentence to keep, cut or rewrite. It is the same check FoxReach runs under every email in the sequence editor.
Spam words are one signal of many.
A single “free” will not send a good email to spam. Modern filters weigh who is sending, whether the domain is authenticated, how the sending inbox has behaved, and how recipients react, far more than any one word. Words matter in aggregate: an email full of hype, urgency and money talk looks like the mail people mark as spam, and gets treated like it.
So fix the foundations first. Run your domain through the SPF, DKIM and DMARC checker, warm up new inboxes for two weeks before a campaign, and keep daily volume per inbox low. Then use this checker to make the email itself read like one person writing to another.
What a cold email that lands looks like.
- Short: most replies come from emails a reader can finish in under thirty seconds, so aim for under about 125 words.
- Plain text, no images, no attachments, and no more than one link. In the first email, none is better.
- One specific reason you are writing to this person, in the first line, instead of “I hope this email finds you well”.
- One small ask, like a question they can answer in a sentence or a 15 minute call.
- A subject that looks like a colleague wrote it. Test yours with the subject line tester.

Questions,
answered.
Words and phrases that show up far more often in spam than in normal mail: false urgency (act now, limited time), money talk (100% free, cash bonus), hype (guaranteed, risk free), pushy calls to action (click here, buy now) and scam language (congratulations, you have been selected). Filters and readers both learn to distrust them.
No. Filters weigh your domain authentication, sending reputation and how recipients react far more than any single word. What hurts is an email that reads like a promotion overall, which is why the deep check grades the whole email and not only the word list.
It judges the wording only, so treat it as a strong hint, not a guarantee. Real placement also depends on whether your domain passes SPF, DKIM and DMARC, how warm the sending inbox is, and your volume. A clean result here plus a passing domain check is the combination that lands.
The word scan never leaves your browser. The deep check sends the subject and body to our server, which has a model grade them and returns the result. We do not save the text, and you do not need an account.
Yes. Tags like {{first_name}} and {{company}} are skipped by the word scan and treated as personalization, which counts in your favor.
The word scan has none. The deep check is free for up to 10 checks a minute and 100 a day from one connection, and takes emails up to 5,000 characters.
