Is your business email set up properly?

Enter your domain and I'll check the five DNS records that decide whether your invoices, quotes, and replies reach real inboxes: MX, SPF, DKIM, DMARC, and basic resolution. Plain-English results, zero signup.

Checks MX, SPF, DKIM, DMARC, and DNS resolution. Pure DNS lookups, nothing touches your website.

What it checks

Your domain's public DNS records. No email is sent.

  • Mail servers are set up (MX)
  • SPF says who can send as you
  • DMARC policy protects your name
  • DKIM signs your outgoing mail
  • Domain resolves to a real address

DKIM is looked up under ten common selector names. If yours uses a custom one the tool will miss it, so confirm that one with your mail provider.
