I am the expert companies bring in when email stops performing — and the stakes are too high to experiment. Over the last 10+ years, I have built and scaled email deliverability infrastructure for some of India's most demanding consumer brands: Tata 1mg, Shiprocket, Bluestone, CaratLane, RedBus, CashKaro, and Abhibus. These are platforms sending tens of millions of emails every month, where a 5% drop in inbox placement translates directly into lost revenue. At Optiserv Consulting, I architected an email deliverability platform achieving 98% inbox placement across 50M+ monthly sends, cut spam complaint rates below 0.1%, and drove a 35% year-on-year increase in email revenue contribution — while simultaneously reducing infrastructure costs by 18% through strategic ESP consolidation. My work sits at the intersection of technical infrastructure (SPF, DKIM, DMARC, BIMI, IP segmentation, Throttling), data governance, and revenue strategy. I do not run campaigns. I build systems that make every campaign perform at its ceiling. If your email program is underperforming — whether that means low open rates, spam folder placement, blacklisting, or simply revenue that should be higher — this is where the conversation starts.
