Domain age, mailbox warm-up cadence, sending IP reputation, authentication record alignment, and bounce handling logic determine whether your emails land in primary inboxes or disappear. I diagnose and fix the system layer, not the surface layer. ENGAGEMENT MODEL I work on project-based and retainer engagements. Discovery calls are structured and outcome-focused. Clients receive a technical audit before any build begins.
