Audit sections
- Inventory every system that sends as the client domain.
- Check SPF, DKIM, DMARC, alignment, policy strength, and DKIM selectors.
- Check PTR, HELO, MX, TLS, DNSBLs, and sending domain health.
- Run a deliverability test for each critical template.
- Validate active campaign lists and segment risky recipients.
- Review DMARC aggregate reports for unknown senders.
- Document fixes, owners, and re-test dates.
Client-facing deliverable
| Section | Evidence | Recommendation |
|---|---|---|
| Authentication | SPF/DKIM/DMARC pass or fail with alignment | Fix gates first |
| Infrastructure | PTR, HELO, TLS, DNSBL, MX | Escalate provider-owned issues |
| Content | Headers, MIME, unsubscribe, links | Fix template-level problems |
| List | Invalid, risky, catch-all, unknown | Suppress and segment |
| Monitoring | DMARC sources and domain scans | Review monthly |
