Google Workspace provides Gmail as a business email solution with professional domain addresses, built-in security, and collaboration features. While primarily designed as a productivity suite rather than a dedicated email marketing platform, many businesses use it for transactional and operational email sending. It offers SMTP access for integration with third-party applications and reliable deliverability infrastructure.
