Case Studies
How we solve email deliverability and security challenges for organizations that depend on email reaching the inbox.
Securing a 364-Domain Portfolio Against Unauthorized Use
A company owned 364 domains but actively sent from only a handful. DMARC monitoring across the full portfolio revealed 79 supposedly dormant domains carrying unauthenticated traffic from IPs worldwide. We locked every dormant domain down with p=reject, null MX, and SPF -all - and corrected two misconfigured active senders along the way
Multi-Tenant Email Platform Serving 1,000+ Senders
A multi-tenant email platform had BAD IP reputation and no visibility into which customers were causing it. We designed an API-driven subuser architecture for per-customer tracking, then recovered the entire network's reputation by fixing its largest sender — 5% → 1.2% block rate, 3x open rates, in two months
Regional Sales Team Email Recovery
Declining inbox placement was silently reducing lead response rates. We diagnosed the root cause, rebuilt sender reputation, and established ongoing monitoring to maintain consistent inbox delivery across Gmail, Microsoft, and Yahoo.
Multi-Location Brokerage with 300+ Agents
Email engagement had plateaued despite solid deliverability fundamentals. We implemented engagement-based sunsetting and audience management that doubled open rates and restored domain reputation to High — while sending 20% fewer emails
