Gmail limits and policies
To help keep systems healthy and your account safe, Google limits the amount of bandwidth, storage space, server requests, and emails that users can send or receive in their Google Workspace account. These limits don't inhibit normal email use, but are designed to help identify any misuse of Gmail.
