Why choose Google Workspace or Zulip?
Google Workspace offers more features like graphic personalization, voice messages, polls, threads, and online document editing. Google Workspace also has multiple workspaces, AI capabilities, and a dedicated customer support team. Zulip, on the other hand, has a free version, but lacks features such as contact management, document management, and task management. While Zulip offers end-to-end encryption and two-factor authentication, Google Workspace offers SAML/SSO authentication and better data and user import options.
