Cold email grader
Paste your cold email and see what a stranger will notice before they decide to answer, graded as you type. Then get an AI review and a tighter version.
Your grade appears here as you type: length, leftover merge tags, stock phrases, the ask, links and tone.
Grading every email by hand? GEOboom finds the pages AI answers cite, writes to each publisher about their own page, and runs the follow-ups, with the mailboxes included.

Questions
What does the cold email grader check?
Ten things a stranger notices before deciding to answer: length, merge tags left in like {{first_name}}, the subject line, stock phrases such as "I hope this email finds you well" or "I came across your website", whether the first line is about you or them, how often you say "we" against "you", how many questions you ask and how big the ask is, links and attachments, exclamation marks and ad words, and paragraphs too long for a phone.
How is the grade worked out?
From the checks: a pass costs nothing, a warning one point, a failure two. No points is an A; eight or more is an F. It counts problems you can fix; it isn't a predicted open or reply rate, which no tool can know from the text alone.
What does the AI review add?
Judgement the rules can't make. It reads the email as the recipient would and says whether there's a real reason it's going to them, whether the offer says what they'd get, whether there's one easy ask, whether your claims need proof, and whether it sounds like a person. Each verdict quotes the line it's about. Then it writes a tighter version.
Will the rewrite make things up?
No. It can cut and reorder, but it only uses what your email says. Where a stronger email would need something you didn't give, like a result or a client's name, it leaves it out and tells you what to add.
Is this for newsletters too?
No, and that's on purpose. Newsletter testers reward emojis, merge tags in the subject and urgency, which make a cold email look like marketing. These checks are for one person writing to another who doesn't know them yet.
Is it free?
Yes. The checks run in your browser, need no sign-in and send your email nowhere. The AI review needs you to sign in with your email, using a code rather than a password, and gives you 20 reviews a day.
