Is the cold email grader free?

Yes. It is completely free with no signup and no limits. Grading runs in your browser, so nothing you paste is uploaded or stored.

What makes a cold email likely to get replies?

A tight, specific subject (3-7 words), a short body (about 50-125 words) built around one relevant reason to reach out, genuine personalization, few or no links, no spam trigger words, and a single low-friction ask. The grader checks each of these.

Will a good grade guarantee my email lands in the inbox?

No. The grader improves the content of your email, but inbox placement also depends on domain reputation, authentication (SPF, DKIM, DMARC), sending volume, and list quality. Treat the grade as a content check, not a deliverability guarantee.

What the grader checks

Subject line — length and specificity; short, concrete subjects get opened.
Body length — cold emails that get replies are usually 50-125 words, not a wall of text.
Spam trigger words — promotional phrases that read as mass marketing and can trip filters.
Deliverability signals — links, ALL CAPS, and exclamation overuse that hurt inbox placement.
Personalization — unresolved merge tags and whether the email centers on the reader.
Clear ask — one specific, low-friction call to action that prompts a reply.
