Reclaim 15GB of Gmail storage by archiving emails to a second account

A method to reclaim 15GB of Gmail storage involves creating a second Gmail account to archive existing emails without deletion. This process utilizes POP3 to transfer messages from the original account to the new archive account, freeing up space. It's also useful for migrating emails from accounts that will be deactivated. The 15GB storage limit applies to Gmail, Google Drive, and Google Photos. Google may delete inactive accounts after two years.
