Start with domain fundamentals
Very new domains carry more risk than aged ones, so the checklist starts before DNS. GTM's readiness model reads registration data to flag young domains, and imported domains without registration records are backfilled from public registry data rather than assumed safe.
- Confirm each domain's age against the workspace's risk assumptions.
- Check registrar lock, nameserver, and WHOIS consistency for imported domains.
- Treat missing registration data as a review item, not a pass.
Move from DNS to inbox evidence
Once MX, SPF, DKIM, and DMARC records resolve correctly, the checklist shifts from domain posture to per-inbox evidence: lifecycle status, managed MTA assignment, SMTP and IMAP connection metadata, credential metadata, and recent smoke-test results.
- Run the DNS checker on every sending domain in the batch.
- Review the workspace readiness report for per-inbox blockers.
- Fix blocked rows before scheduling any seed tests.
Finish with the launch gate
The final checklist item is a gate, not a vibe. First prospect traffic should hard-stop until fresh seed-placement evidence meets the configured threshold and an operator records an explicit go decision. Connectivity smoke tests never substitute for placement evidence.
