Gmail

mailboxEstablished 2004

Developed by Google and launched with a then-unprecedented 1GB of storage, Gmail is now the world’s most widely used email service. It provides a unified communication hub that integrates email, chat, and video calling. The platform is a key driver of the "Software as a Service" (SaaS) model, powering both individual @gmail.com accounts and millions of professional business domains via Google Workspace.
