Email DNS record lookup

Query all email-related DNS records in one comprehensive scan. See MX, SPF, DKIM, DMARC, and more.

What It Does

Run a complete DNS audit for email records. One query returns MX records (mail servers), TXT records (SPF/DKIM/DMARC/verification tokens), A records, CNAMEs, and more.

See what's published, spot missing records, identify conflicts, and verify propagation across global DNS servers.

Why It Matters

Email depends on multiple DNS record types working together. Missing MX? Mail bounces. No SPF TXT? Spam folder. DKIM selector typo? Auth fails.

Rather than checking each record type separately, this tool shows everything at once so you can spot configuration gaps and conflicts immediately.

Key Features

Multi-record type lookup (MX, TXT, A, AAAA, CNAME)
SPF record auto-detection in TXT records
DKIM selector scanning (tries common selectors)
DMARC record lookup at _dmarc subdomain
MX priority sorting
TTL (time-to-live) display
Global DNS propagation check
Record change history

How To Use

  1. 1Enter your domain
  2. 2Click "Check All DNS Records"
  3. 3Review MX records (mail servers)
  4. 4Check TXT records for SPF/DMARC/DKIM
  5. 5Verify A records point correctly
  6. 6Look for unexpected or legacy records
  7. 7Check TTL values for recent changes

Common Issues Detected

  • Missing or misconfigured MX records
  • No SPF record in TXT records
  • Missing DMARC record at _dmarc subdomain
  • Multiple conflicting records
  • Incorrect A record IP addresses
  • Missing nameserver (NS) records

Best Practices

  • Verify MX records point to correct mail servers
  • Confirm only ONE SPF record exists
  • Check DKIM selectors match your mail server config
  • Ensure _dmarc record is present
  • Look for duplicate or conflicting records
  • Check TTL before making changes (lower = faster propagation)
  • Re-check 30 min after DNS updates
