Restoring Inbox Placement & DMARC Alignment for Global B2B Outreach
Estimated Efficiency Gain
Target Primary Inbox Placement
Standardized architectural benchmark under typical production workloads.
The Operational Bottleneck
Key sales proposals and follow-up emails were silently landing in client spam folders. Stricter Google and Yahoo authentication enforcements caused high bounce rates due to missing DMARC and unaligned DKIM records.
Engineering Implementation & Architecture
Conducted a comprehensive DNS and deliverability audit. Configured strict SPF, 2048-bit DKIM keys, and custom DMARC policy with alignment across Google Workspace and transaction relays, backed by domain reputation monitoring.
Target Solution Outcomes & Benchmarks
- Target outcome: Configured to achieve 99%+ primary inbox placement across corporate spam filters
- Target outcome: Enforces strict DMARC alignment (p=reject) and authenticated DKIM cryptographic verification
- Target outcome: Protects proposal reply rates and eliminates silent deliverability drops
