Use Case Guide
DNS Lookup for Email Troubleshooting
DNS is at the center of modern email troubleshooting. MX, TXT, SPF, DKIM, and DMARC records all affect how mail is delivered, validated, and trusted.
Common email troubleshooting checks
- Verify MX records for inbound delivery
- Review SPF policy text
- Check DKIM selector formatting
- Inspect DMARC policy and reporting values
- Confirm TXT records and nameserver consistency
Why it matters
Many email delivery failures come from missing or misconfigured DNS records rather than the mailbox platform itself.
Recommended next steps
Start with DNS lookup, then move into dedicated MX, SPF, DKIM, and DMARC checks to narrow down the exact problem area.
