What is the name of Google's free email service?

The name of Google's free email service is Gmail.

Gmail was publicly introduced on April 1, 2004, initially as a limited beta invitation service. Its launch attracted attention because Google offered 1 GB of storage—far more than many competing services at the time—and because the April Fool's Day announcement made some people suspect it was a joke.

The service grew from an internal Google project led by engineer Paul Buchheit, whose early work focused on making email searchable. Gmail's conversation view, powerful search, spam filtering, and web-based interface helped distinguish it from older webmail services.

Gmail is sometimes confused with Google Workspace. Gmail is the email service itself; Google Workspace is Google's broader suite of business productivity tools, which includes Gmail. Free personal Gmail accounts also share storage with services such as Google Drive and Google Photos.
