Email infrastructure is critical to modern software operations but often overlooked until failures impact customer trust and revenue.
The article argues that email is an underestimated yet essential layer of modern software infrastructure that powers authentication, onboarding, transactions, and customer communications.
While technical teams understand email's complexity involving DNS records, authentication, and delivery systems, most organizations still treat it as a simple background utility rather than production infrastructure.
Companies increasingly face measurable commercial consequences when email fails from reduced activation rates to lost revenue yet many monitor email performance less rigorously than other systems.
The article emphasizes that email should be tested with the same discipline as application code in CI/CD environments and that deliverability directly impacts business metrics like conversion rates and recurring revenue.
