Who Runs the World's Email: Google Leads Microsoft 1.4-to-1 — But Registrar-Bundled Hosting Beats Them Both
We pointed an MX-typed crawl at 390 million registered domains to ask who actually handles the Internet's email. Only 38.7% can receive mail at all. Among those that can, Google Workspace leads Microsoft 365 by 1.4 to 1 (13.2% vs 9.4%) — the inverse of the enterprise market — yet both are dwarfed by registrar- and host-bundled email, which serves nearly a third of all mail-capable domains directly and most of the long tail besides. The result is a geographic map: Google owns the Americas and the developer world, Microsoft owns Northern Europe and the Commonwealth, and domestic hosts own their home ccTLDs. Built from 151 million apex MX records.
