Email disk usage refers to the storage space used by email accounts on the server.
Each email account stores messages, attachments and metadata that count toward your storage limits.

Email disk usage applies to Email Hosting and Web Hosting packages that include email services.

What Uses Email Storage #

Email storage is used by:

• Incoming and outgoing emails
• Attachments
• Spam and Junk folders
• Sent items
• Trash folders

Even deleted emails may still count until removed from Trash.

Mailbox Storage Limits #

Each email account has:

• A defined mailbox limit
• Storage usage counted within your package limits

When a mailbox reaches its limit:

• Incoming emails may be rejected
• Senders may receive bounce messages

This affects email delivery immediately.

Where to View Email Disk Usage #

You can view usage:

• In cPanel under Email Accounts
• Per individual mailbox

This shows how much storage each account uses.

Managing Email Disk Usage #

To reduce usage:

• Delete old emails
• Empty Trash and Junk folders
• Remove large attachments
• Archive emails locally if needed

Regular cleanup prevents delivery issues.

Spam Folder and Storage #

Spam emails:

• Still use storage space
• May accumulate over time
• Are usually auto-deleted after a retention period

Check spam folders periodically.

Attachments and Large Files #

Attachments:

• Consume significant storage
• Are often the main cause of full mailboxes

Avoid sending or storing large files via email when possible.

Email Disk Usage vs Hosting Disk Usage #

Email storage:

• Is part of your total package storage
• Is separate from website file usage
• Can impact other services if limits are reached

Monitor usage regularly.

Common Issues #

• Mailbox full errors
• Emails bouncing unexpectedly
• Storage not freeing up after deletion
• Large attachments filling mailboxes

Most issues are caused by unmonitored usage.

Responsibility Notice #

You are responsible for:

• Monitoring mailbox usage
• Managing storage limits
• Cleaning up unused emails

ProRedLine does not automatically increase mailbox storage.
