After Google Hangouts was closed in November 2022, Google Meet and Chat became the main communication platforms for the company. Google Chat, specifically, has been customized for Google Workspace business users, offering text-based communication and supporting up to 500,000 members in spaces. This increase in capacity is beneficial for large corporations with a global presence.
Google Chat’s integration with various Workspace apps sets it apart from competitors like Slack and Microsoft Teams, providing a seamless communication experience. Additionally, Google Group members can now be added to spaces, with the time required to do so varying based on the number of members. This new feature is already available to Google Workspace customers and will be rolled out starting June 26, 2024. Users may need to wait until they can access it.
