About This Feature

Overview

Storage Space helps you check how much mailbox capacity is already used, what the total storage limit is, and how much space each mailbox area takes up. From the storage page, you can directly clear items such as Drafts, Deleted, or Spam to free up mailbox space and keep email sending and receiving running smoothly.

Core capabilities include:

View the total mailbox space and storage usage by location so you can quickly identify pressure on your mailbox.
Clear storage directly from the storage page without switching between multiple pages.
Confirm cleanup actions to release space for routine mailbox maintenance.

Capability Summary	In WPS Mail settings, you can view the total storage limit and usage by mailbox area, then directly clear Drafts, Deleted, Spam, and similar content.	Outlook provides a mailbox storage page where users can review folder usage and delete items from specific folders to free space.	Gmail storage is part of shared Google account storage. Users can empty Trash and Spam, delete large emails, and buy more storage when needed.	Current official Notion Mail guidance focuses on export and shutdown steps. Mail history remains in Gmail, and there is no equivalent standalone mailbox storage cleanup page described in the official article used here.	Adobe Acrobat provides cloud file and folder management in Adobe cloud storage, which is centered on document storage rather than mailbox cleanup.
WPS Advantages	Advantage: WPS brings storage viewing and cleanup into the mail settings page, which fits routine mailbox maintenance.	Compared with WPS: Outlook also supports mailbox storage review and cleanup, but its guidance emphasizes mailbox quotas and folder-level cleanup.	Compared with WPS: Google focuses on account-level shared storage across Gmail, Drive, and Photos instead of a mailbox-only storage page.	Compared with WPS: Notion Mail public guidance is currently centered on migration and export, with less official detail about mailbox storage cleanup.	Compared with WPS: Adobe's official capability is oriented toward document cloud storage management rather than email mailbox storage management.

Overall Conclusion
WPS Storage Space is a practical fit for users who want to check mailbox usage and clear space from within the mail interface. Compared with shared account storage or document cloud storage workflows, it stays focused on mailbox maintenance as a specific task.
