Check domain

What's publicly exposed?

SPF and DMARC records are public DNS TXT records — anyone can look them up. Type a domain below and this runs the lookup in your own browser, live, against Cloudflare's public DNS resolver. Nothing is sent anywhere else or stored.

This checks SPF and DMARC only. DKIM isn't included — verifying it requires knowing the sender's selector, which can't be guessed for an arbitrary domain, so there's no honest way to check it generically here.
