Rewrite & send
Fix the flags, verify your list, and land in the inbox.
Most cold emails don't fail because of one big mistake — they bleed replies through a dozen small ones: a spam word in the subject, two links too many, no real personalization, a wall of text, a vague ask. Individually they seem harmless. Together they land you in spam or in the trash.
This free cold email grader scores your subject line and body against the rules that actually decide whether you get a reply, highlights every problem, and tells you exactly how to fix it — so you can rewrite with confidence before you hit send.
A great email still won't land if you're sending from an unauthenticated domain, to unverified addresses, out of a cold inbox. Deliverability is a system: clean copy, a verified list, authenticated domains and warmed-up inboxes all working together.
Emailchaser handles the whole system — warmup, inbox rotation, verification and sending — on a flat plan with unlimited seats. Grade your copy here, then let Emailchaser get it to the inbox.
How does the cold email grader score my email?
It checks your subject line and body against the rules that actually move reply rate and deliverability: spam trigger words, number of links, personalization, length, exclaimation marks, all-caps, a single clear ask, readability and subject-line quality. Each issue lowers the score, and you get a 0–100 grade (A–F) with a specific fix for every problem.
What makes a good cold email score?
Aim for a B or better. The strongest cold emails are 50–125 words, have zero links in the first touch, one clear ask, real personalization, no spam trigger words, and a short human subject line. The grader shows you exactly where you're losing points.
Will a good grade guarantee my email lands in the inbox?
A clean, well-written email is a big part of it, but deliverability also depends on authenticated sending domains (SPF, DKIM, DMARC), warmed-up inboxes, a verified recipient list and low bounce rates. Grade your copy here, then verify your list and warm your inboxes to actually reach the inbox.
Is the cold email grader free?
Yes — it's free, needs no signup, and runs entirely in your browser. The subject line and body you paste are never sent to a server.
