Storage Usage
Checking Your Storage Usage
To view how much storage your archive is consuming:
- Navigate to Settings > Billing
- The billing overview displays your total storage usage alongside your storage allocation
- A progress bar shows the percentage of your total allocation in use
You can also see a more detailed breakdown in Settings > Billing, which shows how storage relates to your license calculation.
What Counts Toward Storage
Storage usage is calculated based on the total size of all archived email messages, including:
- Message bodies - The text and HTML content of each email
- Attachments - Files attached to archived messages (documents, images, PDFs, etc.)
- Message metadata - Headers, envelope information, and indexing data
Messages are stored in a compressed and encrypted format. The storage usage displayed in your account reflects the size of the original messages before compression, so your actual consumed storage may be somewhat lower than the displayed figure.
Per-License Storage Allocation
Each license on your plan includes a fixed amount of storage:
| Plan | Storage per License |
|---|---|
| Starter | 10 GB |
| Business | 25 GB |
| Enterprise | Custom |
Your total storage allocation is the number of licenses multiplied by the per-license storage amount. For example, if you have 20 licenses on the Business plan, your total storage allocation is 500 GB (20 x 25 GB).
How Storage Affects Licensing
If your storage usage exceeds the allocation provided by your active user count, additional licenses will be added to cover the difference. The formula is:
storage_licenses = ceil(total_storage_gb / storage_per_license_gb)
Your billed license count is always the higher of your active user count or your storage-based license count. For example, on the Starter plan with 10 active users and 150 GB of storage, you would be billed for 15 licenses (ceil(150/10) = 15, which is greater than 10).
Managing Storage Growth
Email archives grow over time as new messages are continuously archived. Here are some strategies to manage storage growth:
- Review retention policies - Configure automatic deletion of messages older than your required retention period to prevent unbounded growth
- Monitor usage trends - Check your storage usage regularly to anticipate when you might need additional licenses
- Consider upgrading - The Business plan provides 25 GB per license instead of 10 GB, which can be more cost-effective if storage is driving your license count
Storage and Compliance
Be mindful that reducing storage through aggressive retention policies must comply with your legal obligations. Many jurisdictions require email retention for specific periods (e.g., 6 or 10 years for business correspondence in Germany). Always consult your compliance team before adjusting retention policies.
