In this article, we will explain the needs & methods to delete all mail from Gmail at once after taking their backup. We’ll provide step-by-step execution of backup and deleting process of emails from the Gmail server to free up some space.

What are the Reasons for Backup?

Gmail is essentially the most commonly used email client because it’s free, provides decent storage space and many applications for its users. Gmail shares its storage space among emails, contacts, events, drives, and chats in the cloud. Since the storage is limited to 15 GB, it’s necessary to free up space for continuing the email service.

Additionally, Gmail is somewhat prone to hacking, users prefer to keep a local backup of all their Gmail data. As we all know that in the past Gmail has many outages, which has disrupted the basic functioning of Gmail. And further, this leads to inaccessibility to the Gmail account. Even there are some cases, in which they have completely lost their complete Gmail data.

If you consider both cases then it is a good practice to further safeguard data from storage maxed out or cyber-theft. So, it is preferable to backup and delete all mail from Gmail at once to get some more space.

Limitations of the Manual Method

  • The Gmail backup creates files in MBOX format, which is not perfect for every user.

  • In the backup, we will not include Spam and Trash folders
