Email Security Check
Check a domain's SPF, DKIM and DMARC records, and see in plain English what each one means for your email.
A web address or an email address works too.
Only the domain you enter is sent, to Cloudflare's public DNS resolver (1.1.1.1): this page looks up DNS records for it, for names built from it (such as _dmarc.example.com.au) and for the domains its SPF record points to. Cloudflare also sees your IP address, as with any web request, and says it deletes its resolver logs within 25 hours (Cloudflare's resolver privacy policy). This page stores nothing.

We set up SPF, DKIM and DMARC for our clients. Tell us your domain and roughly how many people you have, and we usually respond same day.
