Free Newsletter & Email Capture Checker
Enter any website URL and get a plain-English email-capture score — 12 automated checks for the newsletter signup placement, lead magnet, form friction, double opt-in, and consent language that turn visitors into subscribers. Heuristics are stated as heuristics throughout.
Privacy: we fetch the URL you enter to run the checks, but we never store it. The only thing recorded is an anonymous "grader run" for our own stats. Public websites only.
What the checker checks
Can visitors join?
A newsletter signup form that actually exists and sits near the top of the page, plus a backup signup in the footer for the visitors who scroll past the hero.
Would anyone bother?
A lead magnet that gives people a reason to trade their address, anti-spam reassurance next to the form, at most 2 fields to fill, and a form with a real action and method.
Is the list healthy?
A signaled thank-you flow, double opt-in mentioned, subscriber proof near the signup, no pre-checked consent boxes, and explicit consent language.
