SH Consulting: Email Security & Deliverability Expert Review

SH Consulting helps organizations whose legitimate email is under attack or failing to reach the inbox. As providers like Google and Microsoft tighten defenses against bad actors, poorly configured senders get caught in the crossfire—35% of companies are being spoofed without even knowing it. SH Consulting takes a security-first approach, building infrastructure that stops abuse while ensuring delivery. They improve and rebuild your existing stack rather than replacing it, preserving flexibility among email partners and avoiding vendor lock-in. Services span four areas: Email Security, including authentication deployment, spoofing and phishing monitoring, and forensic analysis; Email Deliverability, including full-stack audits, blacklist remediation, and infrastructure architecture; Security Research, with continuous vulnerability research across email servers, DNS infrastructure, and authentication protocols; and System Consolidation, unifying multiple ESPs, legacy mail transfer agents, and fragmented tools into scalable systems. Their Diagnose, Fix, Protect model starts with deliverability and DNS security audits, moves through crisis recovery and authentication setup, and continues with managed deliverability and ongoing security monitoring. Clients range from fintech startups and real estate brokerages to government agencies. The team includes a former SendGrid Head of Deliverability who managed 20 billion monthly emails, with direct relationships at major mailbox providers for escalation and resolution. Reported client results include 70%+ open rates versus a 30% industry average, 15%+ conversion rates on non-transactional email, and 0.3% spam complaint rates versus a 1.5% average.
