Executive Summary

Mid-market organizations that send marketing and transactional email often lack the expertise and tooling to reliably implement and monitor SPF/DMARC/DKIM, leaving IT and security teams spending time chasing spoofing issues and marketers worried about delivery risks. That gap drives exposure to phishing, business email compromise, and brand damage, especially as regulators and partners increasingly expect published authentication policies. You could build a SaaS that packages enterprise-grade email-auth monitoring and enforcement for mid-market buyers—automated domain scanning, actionable analytics, policy progression guidance, compliance-ready reports, automated remediation playbooks, and partner-ready white-label/MSP integrations—priced toward the $900 ACV segment. Prioritize connectors to major ESPs/IdPs and a low-touch onboarding flow so customers see outcomes in weeks, not months. The market looks attractive now: a roughly $4.5B addressable opportunity (5M organizations × $900 ACV) driven by rising phishing/BEC trends and growing regulatory and brand-protection pressure, and channel tailwinds from MSPs and hosting providers. You can compete by focusing on mid-market usability and partner distribution—simpler onboarding, policy automation, and white-label capabilities—while being upfront about challenges: the competitive landscape is medium, and success requires nailing false-positive avoidance, cross-provider integrations, and clear ROI messaging.
