Email Is Not Legacy. It's Infrastructure.
Security Boulevard, Tuesday, January 13th, 2026
Email doesn't always get the respect it deserves. In a world brimming with slick collaboration platforms, instant messaging apps, and AI copilots, email is often seen as old-fashioned-a legacy system clinging on in the face of faster, flashier alternatives.
But that view is at best outdated, and at worst, dangerously misinformed.
Email has been declared dead more times than we can count. Yet it remains the backbone of modern business-essential, universal, and remarkably resilient. Far from being a relic, email continues to operate as critical infrastructure. It underpins everything from vendor communication to customer support to compliance workflows. Email hasn't faded-it's become foundational.
