Will your cold email land, or read like AI wrote it?

A cold email gets filtered or ignored for three kinds of reason: words that spam filters weigh, wording that reads as AI-written or templated, and an email about the sender instead of the reader. Paste yours to see each problem marked in place, with a reason and a fix. Free, no signup, nothing leaves your browser.

Verdict

Paste an email to check it.

Or try the bad example.

Monty writes each email for one person, then checks it before it sends.

An unfilled merge field or leftover placeholder text stops an email from sending and holds it for you to fix, and a phrase from your “Never say” list holds it for your review. When Monty sends on its own, spam words, shouting and shortened links count against an email, and one that scores too low waits for your approval.

What it checks

Three questions, checked by fixed rules.

Every check is a fixed rule that runs in your browser. Nothing is sent to an AI model, so the same email gets the same result every time. Phrases match whole words only, so “They” is never read as “hey”.

1. Will it land

  • Spam phrases. Money promises (“risk-free”, “100% free”, “money-back guarantee”), pressure (“act now”, “limited time”, “last chance”), prize bait (“you have been selected”), guarantees (“guaranteed results”) and link bait (“click here”). Ordinary sales words like demo, pricing and trial are left alone.
  • Shouting. Any word of five or more capitals in the body, or four or more in the subject. Common acronyms such as CRM, SaaS, ROI and GDPR are allowed. Repeated punctuation like “!!” or “?!”, and any exclamation mark in the subject.
  • Links. Link shorteners such as bit.ly or tinyurl are flagged every time. More than one link in a first email reads as bulk mail; one link is noted, because none reads more personal.
  • Fake reply. “Re:” or “Fwd:” at the start of a first email’s subject.
  • Leftover placeholders. [Company], [First Name], [INSERT …], {first_name} and ${name} are errors. {{first_name}} is flagged as a merge tag to check in a preview.
  • Subject length. Over 50 characters is cut off on a phone.

2. Does it sound like AI or a template

  • Stock openers. “I hope this email finds you well”, “I wanted to reach out”, “My name is … and I”, “I came across your”, and a “Quick question” subject.
  • AI words. Each is marked. One or two is a word; three or more is a voice, and they are all raised to “worth fixing”. The full list: i hope this email finds you well, i hope this message finds you, hope this finds you well, hope all is well, i wanted to reach out, i am writing to, i'm writing to inform you, per our conversation, as per our discussion, furthermore, moreover, additionally, in addition to the above, it is worth noting, it should be noted, it's important to note, with that being said, that being said, needless to say, leverage, synergy, synergize, streamline, optimize, utilize, facilitate, implement, paradigm, holistic, comprehensive solution, best-in-class, cutting-edge, state-of-the-art, robust, scalable, innovative, revolutionary, game-changing, seamless, seamlessly, effortlessly, empower, empowering, delve, tapestry, realm, ecosystem, landscape, actionable insights, unlock, unlocking, single source of truth, all-in-one platform, leading provider, touching base, touch base, just checking in, checking in on this, quick question.
  • AI sentence shapes. “It’s not just X, it’s Y”; a closing flourish (“the possibilities are endless”); announcing your research (“Saw you’re hiring…”); congratulating them on their own news; “serves as a” for “is a”; “a testament to” and “plays a key role”; throat-clearing (“Here’s the thing”); uncited “studies show”; “the implementation of”; stacked hedges (“could potentially”); three adjectives in a row.
  • Rhythm. Four or more sentences of nearly the same length, and three or more long dashes in a short email.

3. Will they care

  • One ask. No question or request the reader can answer is flagged, and so is more than one. Asks are counted per sentence. More than two question marks is also noted.
  • Length. Over 80 words is noted; over 120 is too long for a first email.
  • Who it is about. The first sentence after the greeting starting with I, we, my or our. It is the line their inbox preview shows.
  • Something checkable. Numbers, money, months and names, counted per 100 words in emails of 25 words or more. Under one per 100 words, the email could go to any company. Stock claims like “take your business to the next level” are marked too.

What it cannot check: your domain setup, your sender reputation, your list, or whether the offer matters to the person reading. A clean result means the words are not the problem, nothing more.

Common questions

+How do I check if my cold email will go to spam?

Check the words first: money and pressure phrases such as "act now", "risk-free" or "guaranteed results", words in capitals, repeated "!!!", link shorteners such as bit.ly, and more than one link. This checker marks each one. A clean result only means the words are not the problem. Domain setup and sender reputation decide the rest, and no copy checker can see those.

+How can you tell if a cold email was written by AI?

Look for three things: stock words (leverage, streamline, seamless, unlock), stock openers ("I hope this email finds you well"), and stock sentence shapes, such as "It's not just a tool, it's a partner", stacked hedges like "could potentially", or every sentence the same length. The shapes matter most, because rewording a sentence does not change its shape.

+How long should a cold email be?

This checker flags a first email over 80 words and calls it too long over 120. Under 80 words fits on one phone screen. Follow-ups should be shorter still. Keep the subject under 50 characters so it is not cut off on a phone.

+Why does it flag {first_name} or [Company]?

Because a placeholder that does not get filled goes out as it is, brackets and all. Single braces and square brackets are flagged as errors. Double braces, like {{first_name}}, are a real merge tag in most sending tools, so they are flagged as something to check in a preview, not as a mistake.

+Does a clean result mean people will reply?

No. It means none of these checks fired. Whether someone replies depends on who you send it to and whether what you offer matters to them, and no checker can see either.

+Is my email stored or sent anywhere?

No. The check runs in your browser. The email is not sent to a server and is not put in the page address.
