Document your full email infrastructure in one place

1-2 hr Impact: medium Effort: low ✓ Manual completion

Documenting your complete email infrastructure in one place, every sending tool, every DNS record, every authentication setting, turns scattered tribal knowledge into a real reference anyone (including future you) can consult without having to reconstruct it from memory.

Email infrastructure tends to accumulate complexity over time as tools get added, and without documentation, troubleshooting a future deliverability issue means starting from scratch each time.

How to do it

  1. 1
    List every tool that sends email as your domain
    Main provider, marketing tools, transactional services, anything with sending access.
  2. 2
    Document your actual DNS records
    SPF, DKIM selectors, DMARC policy, MX records, all in one reference.
  3. 3
    Note who has administrative access to what
    Which accounts control which pieces of this infrastructure.
  4. 4
    Keep it updated as things change
    A stale document is only marginally better than no document, this needs to be a living reference.
