The real problem
Your ESP dashboard measures what it sends. Inbox providers measure what they receive and trust. Those are different measurements entirely. Most SaaS founders only find out when revenue drops.
- What's inside —
Five sections.
Every revenue leak covered.
Section 01
Authentication Failures
SPF, DKIM, and DMARC — not as compliance checkboxes but as revenue protection. How they break after domain changes, ESP migrations, and new tool installs. What each failure costs.
Section 02
List Health Decay
Why your engaged segment is probably not who you think it is. The Apple MPP problem explained. How to rebuild your segments around the only signal that is still honest.
Section 03
Flow Logic Gaps
Time-based vs behaviour-based onboarding. Flow cannibalization. Why a sequence that worked at 1,000 users breaks at 10,000. How to implement waterfall segmentation without a full rebuild.
Section 04
Integration Risks
Every tool you add that touches email introduces risk. How third-party apps silently create new sending sources, break existing authentication, and bleed domain reputation into transactional email.
Section 05
The Diagnostic Stack
Google Postmaster, MXToolbox, Mail-Tester — what each one shows, what to look for, and the exact Claude prompt that turns raw signal data into a prioritized fix list.
Framework
