Use DNS and domain data to evaluate project domains before building campaigns.
Why this matters
Email DNS records are small pieces of public infrastructure, but they tell a practical story about how a domain is operated. A domain with thoughtful MX, SPF, DMARC, and DKIM records is usually easier to evaluate than one with missing or contradictory records.
What to check
- Confirm MX records point to the expected mail provider.
- Review SPF for a single clear policy and remove stale senders.
- Check DMARC policy strength and reporting readiness.
- Verify DKIM when you know the selector from the mail platform.
Recommended workflow
Start with the free Email DNS Checker for a single-domain view. For broader research, compare the domain against NewDomainData datasets so you can understand category, TLD, expiration, and market context.
