DNS Record Inspector

Enter any domain and instantly see everything in its DNS — SPF, DKIM, DMARC, MX, BIMI, MTA-STS and more, grouped and explained in plain English. Works for any registrar or host.

Try:

All record types

A, AAAA, MX, TXT, NS, SOA, CAA — queried simultaneously so results load in one shot.

DKIM selector scan

Scans 22 common DKIM selectors (Google Workspace, Microsoft 365, SendGrid, Postmark and more) to find active keys.

Works everywhere

Namecheap, GoDaddy, Cloudflare, Microsoft 365, Google Workspace — DNS is always public regardless of registrar or host.

Monitor your DNS records automatically

Mailflo watches your SPF, DKIM, DMARC and MX records continuously — alerting you the moment something changes or breaks before it affects your campaigns.
