Cold Email Doctor
Score a cold email for spam, replies, and CAN-SPAM
Paste a subject line and body. Get three separate scores - will it reach the inbox, will anyone reply, and is it lawful to send - plus a ranked list of what to fix, worst first. No account, no server, no analytics. The extension makes no network requests at all, so your prospect list has nowhere to go.
I built this after noticing that cold email tools check one thing and call it a score.
An email can fail in three unrelated ways. It can be filtered before anyone sees it. It can land and get ignored. Or it can be perfectly written and still be missing an opt-out and a postal address, which is a compliance problem, not a copywriting one. A single number hides which of the three is actually broken, so this scores them separately.
The compliance axis is the part I have not seen elsewhere. It checks for an opt-out instruction, a postal address, an identifiable sender, and a subject line that is not a fake "Re:". It is a drafting aid, not legal advice — but most people find out they were missing one of those the hard way.
One design decision worth mentioning: it makes no network requests. Not analytics, not error reporting, not an AI call. Everything runs in your browser. Your prospect list is your business, and I did not want a copy of it. That also means there is no signup and nothing to cancel.
Free. Happy to add rules if you tell me what your filters keep catching.
