Hidden among advertisement, social media notification emails, and various one-time confirmation emails are old bank account statements, login credentials to various accounts, and personal and work-related messages.

When that happens, the natural reaction of most users is to delete as many old and useless messages as possible.
Because those 15 gigabytes of storage space that all users get to enjoy for free are shared across all Google services, including Google Drive and Google Photos, a Gmail inbox can reach its capacity quicker than it might seem at first. With so much free space, it’s no wonder that Gmail users sometimes neglect inbox management, never deleting old emails, and seldom unsubscribing from newsletters they are no longer interested in.
