Check your domain
Enter your domain above and hit Check Now. We’ll analyze SPF, DKIM, and DMARC, then show clear fixes.
What we do
- DNS-only checks: TXT records for SPF, DKIM selectors, DMARC policy.
- Alignment heuristics using your From domain and DMARC modes.
- Optional weekly re-checks with email/Slack alerts via cron.php.
- Exports: JSON, CSV, and a simple PDF report.
We never send emails or modify your DNS. Ensure your server can resolve public DNS.
