Gmail and Google Workspace are both integral to Google's suite of services, but they cater to different needs. Gmail is a free, personal email service designed for individual users, offering a user-friendly interface and robust features like spam protection and search capabilities. In contrast, Google Workspace (formerly G Suite) is a comprehensive suite for businesses and teams, encompassing Gmail along with professional tools such as Google Drive, Google Meet, and Google Calendar. Google Workspace provides enhanced administrative controls, additional storage, and advanced collaboration features tailored for organizational use.
