Why is creating a Google Group considered more effective than Gmail’s contacts group?

Creating a Google Group is considered more effective than Gmail’s contacts group primarily because Google Groups provide a unique email address for the group as a whole. This allows users to send emails to all group members by simply emailing this single address, rather than having to input individual email addresses for each recipient. In addition, Google Groups can handle a large number of recipients without running into the sending limits imposed on individual Gmail accounts. This feature makes communication simpler and more efficient, especially for larger teams or organizations. The custom email address of a Google Group streamlines the process of reaching out to a large audience at once, significantly enhancing versatility in communication compared to a standard contacts group in Gmail.
