How cloud storage and attachment extraction works
Cleanbox automatically extracts attachments from incoming emails and stores them in encrypted cloud storage, organized by contact. This gives you a searchable archive of every file you have ever received — without manually downloading anything.
How it works
- An email with attachments arrives at one of your aliases
- Cleanbox processes and delivers the message as normal
- After delivery, a background process extracts all attachments
- Files are stored in cloud storage, grouped by the sender contact
- You can browse and download them from the Cloud section in your dashboard
Enabling and disabling cloud storage
Per contact
Cloud storage can be toggled on or off for individual contacts from their detail page. This is useful if you want to save attachments from business contacts but skip personal conversations or high-volume newsletter senders.
Team-wide
Cloud storage can also be toggled at the team level from your settings. When disabled team-wide, no attachments are extracted regardless of per-contact settings.
Browsing your files
The Cloud section in your dashboard shows all contacts that have attachments stored. For each contact you can see:
- Number of stored files
- Total storage used
- File list with name, size, and date received
Click any file to download it. Files are stored in their original format — PDFs, images, documents, spreadsheets, archives, and any other attachment type.
Storage limits
| Plan | Cloud storage |
|---|---|
| Free | — |
| Personal | 1 GB |
| Premium | 10 GB |
| Advanced | 50 GB |
| Enterprise | 200 GB |
Cloud storage is independent of message retention. When a message expires from your retention window, already-extracted attachments remain in cloud storage until you manually delete them or your quota is exceeded.
Privacy and security
All stored files are encrypted at rest on DigitalOcean Spaces. Files are only accessible through your authenticated Cleanbox dashboard — there are no public URLs or shared links. When you delete a file, it is permanently removed.
