Gmail or google mail

A subtle distinction!

Gmail and Google Mail are actually the same thing. Gmail is a free, web-based email service provided by Google. It was launched in 2004 and has since become one of the most popular email services in the world.

The term "Gmail" is often used informally to refer to the service, while "Google Mail" is a more formal or technical name that refers to the same service. Both terms are widely recognized and used interchangeably.

So, whether you say "Gmail" or "Google Mail", you're referring to the same email service provided by Google!
