Gmail Analytics is a free Chrome extension developed by ubershmekel that provides users with insightful statistics about their Gmail inbox. This add-on allows users to easily identify and analyze their email activity, making it a valuable tool for those who want to gain a deeper understanding of their inbox.

With Gmail Analytics, users can quickly see who is sending them the most emails and even filter their inbox based on the sender. The extension conveniently displays the most frequent sender at the top of the inbox, to the right of the search bar. It's important to note that the statistics are based on the current page of emails and not the entire inbox. However, the developer has expressed the possibility of adding more features in the future if the extension gains popularity.
