PLEASE NOTE: When deleting mail in bulk, exercise extra caution, as these methods will remove mail immediately and permanently.

For those using Network Dynamics Business Hosting, you can utilize the ‘Email Accounts‘ and ‘Email Disk Usage‘ tools in cPanel to efficiently identify email accounts that consume significant disk space.

3. Scroll down and click ‘Update Email Settings’ when you’re done.

PLEASE NOTE: When allocating storage space to email addresses, bear in mind that the overall hosting service’s disk storage limit still applies. Consequently, plan your allocations carefully. For example, Startup has 5GB, Business has 10GB, and Business Plus has 20GB. Setting an email address to ‘unlimited’ allows usage only up to the total storage available in your plan.

For example, if your hosting plan offers 10GB, then setting an address to unlimited permits it to utilise the full available capacity.

We strongly recommend setting reasonable email storage allowances to prevent email accounts from using up space needed for other hosting functions, such as website files and databases. This helps ensure optimal performance and prevents storage issues.

To view the disk usage of an email address on a per-folder basis: #

Please note: when deleting mail in bulk, exercise extra caution. This method causes immediate and permanent removal; therefore, double-check your selections before proceeding.

  • Once an address is chosen, click ‘Manage‘ to the right of the folder to reveal more options.
  • For example, the john_doe@ address has 1 INBOX message, 0 in Sent and Spam folders, using 60.77KB disk space.
