Google Workspace (formerly G Suite) is a collection of cloud-based productivity and collaboration tools designed for businesses, allowing them to use Gmail with their custom domain name (@yourcompany.com). It offers various features such as integration of multiple tools, enhanced security measures, and advanced management controls. The cost of Google Workspace varies depending on the plan, ranging from $6 to $18 per user per month. To set up a business Gmail account, one needs to create an account, enter their company name, domain, and address, and then verify their domain ownership. This can be done manually or automatically by Google if the domain is already hosted with GoDaddy. Once verified, users can add team members, customize settings, and automate tasks using tools like Zapier.
