Email DNS Lookup

Enter a domain to inspect its email DNS configuration — MX mail routing, SPF sender policy, DMARC enforcement, and BIMI brand logo records — with instant validation and alerts for common misconfigurations.

How to Use the Email DNS Lookup Tool

Enter any domain name (e.g. google.com) and click Lookup. The tool queries the selected DNS-over-HTTPS provider directly from your browser — no data is sent to EpicTools servers.

What Each Record Means

  • MX (Mail Exchanger) — Lists the mail servers responsible for accepting email for the domain, sorted by priority. A missing MX record means the domain cannot receive email.
  • SPF (Sender Policy Framework) — A TXT record that specifies which servers are authorized to send email on behalf of the domain. Helps receiving servers identify and reject spoofed email.
  • DMARC (Domain-based Message Authentication, Reporting & Conformance) — Builds on SPF and DKIM to tell receiving servers what to do with mail that fails authentication. Policies range from none (monitoring) to reject (full enforcement).
  • BIMI (Brand Indicators for Message Identification) — An emerging standard that lets brands display a verified logo in supporting email clients (e.g. Gmail). Requires a valid DMARC policy of quarantine or reject.

Understanding Alerts

  • Error — A misconfiguration that actively harms deliverability or security.
  • Warning — A weak setting that should be strengthened over time.
  • Info (✓) — Best-practice configuration is in place.

DNS Provider

Lookups use DNS-over-HTTPS (DoH) — either Cloudflare's 1.1.1.1 or Google's dns.google. Both are free public resolvers. Switch providers if you get unexpected results or want to verify consistency.

About This Tool

This email DNS lookup tool works as an MX record checker, SPF record validator, DMARC record lookup, and BIMI record tester. Enter any domain to instantly retrieve and analyze all four email-related DNS records side by side, with scoring and actionable alerts for misconfigurations.

Essential for email deliverability troubleshooting, domain email setup verification, and anti-spoofing compliance. Use it to diagnose why emails are landing in spam, verify a new domain’s email configuration before go-live, or audit email security for DMARC enforcement and DKIM alignment.
