Questions
Frequently asked questions
Is my email sent anywhere?
No. The checker runs entirely in your browser. Nothing you paste is uploaded or stored.
What makes a good cold email score?
Short (roughly 50–125 words), a specific subject line under about 50 characters, at least one personalization detail, one clear question as the call to action, few links, and no spammy phrases.
Does a high score guarantee replies?
No. Relevance to the reader matters most. The score catches common problems that hurt deliverability and reply rates, so you can fix them before sending.
