Email Notification for Quotas over the Limit
Note: For performance purposes, cPanel does not immediately check and send notifications. Warnings and suspensions may not occur till several hours after the notification limit is reached. At this time cPanel will only send out notifications for the highest warning level reached.
The type of hosting plan you have can dictate how you are notified via email by your hosting panel about overages in bandwidth, disk space and email quota.
Shared Web Hosting - VPS and Dedicated Hosting
If the limit of an account or email is about to be exceeded, then the system can automatically send a notification.
The cPanel user can go to cPanel and update the contact email. The icon is at the top and cPanel will send email notifications to you at 70% and 85% capacities for disk space, bandwidth, and email quotas.
