Is your domain SPF, DKIM and DMARC ready? Free check. No sign up. No sign in.

100% free. No sign up. No sign in. Runs in your browser.

Enter any domain and we'll resolve its SPF record, look for DKIM signing keys on common selectors, parse the DMARC policy, and check the domain's resolved IP against six major blacklists (Spamhaus, SpamCop, Barracuda, SORBS, PSBL, Manitu). All four checks run in parallel via Cloudflare DNS over HTTPS. No data leaves your browser.
