Why Doqubox?

Still chasing documents through email threads and attachments? Doqubox gives you one controlled place to request, receive, and send sensitive files.

Sensitive documents do not belong in email

Email creates copies, uncertainty, and cleanup work when sensitive client documents are involved. And without a secure alternative, clients often have to use their own personal inbox to send confidential files.

Scattered attachments

Documents end up in inboxes, sent folders, archives, and backups where they are hard to control.

Missing files and follow-ups

Clients forget attachments, send the wrong version, or need another reminder before a case can move forward.

No safe route for clients

When you ask for email attachments, clients are pushed toward their own free or personal email service. That route is often not suitable for sensitive documents.

Compliance gets messy

Retention periods, deletion, and secure storage are harder to prove when data is spread across mailboxes.

The solution - Doqubox

With Doqubox, every file moves through a secure client workflow that is clear for clients and controllable for your organization.

Targeted document requests

Ask for exactly what you need with a clear checklist, instructions, and automatic reminders.

A secure upload route for clients

Clients receive a clear upload link and do not need to send confidential documents from their own inbox.

End-to-end encrypted

Files are encrypted client-side and document content remains shielded at the platform level.

Expiry and revocation

Automatically expire documents and revoke incorrectly sent files when needed.

How it works

Three ways to keep client documents out of email

Passive receiving

Your Doqubox address

Share your personal upload link on your website, in your email signature or business cards. Clients can always securely send documents to you.

  • One link for all clients
  • Perfect for your website and email signature
  • Clients upload whenever they want
Active requesting

Send a document request

Send a targeted request to your client specifying exactly which documents you need. They receive a link with clear instructions.

  • Specify which documents you need
  • Client won't forget anything with a clear checklist
  • Send automatic reminders
Secure sending

Send files securely

Send sensitive documents to clients through a protected link instead of attaching files to email.

  • Expiring download links
  • Revoke files sent by mistake
  • Optional SMS verification

Built for professional client communication

Give clients a simple upload experience while your organization keeps control over branding, access, and retention.

Custom branding

Use your own logo so every upload and download page feels familiar to your clients.

Own upload address

Run your portal and email flow on a recognizable domain, such as documents.yourcompany.com.

Team inbox

Work with multiple users in one account and keep incoming client documents organized.

SMS verification

Add an extra verification step before clients can access sensitive files you send.

EU hosting

Store client data on European infrastructure that helps meet GDPR requirements for secure document exchange.

Clear retention

Use automatic expiry to avoid keeping sensitive documents around longer than necessary.

Secure document exchange that grows with your work

Start free to receive sensitive files. Upgrade when you need to request, send, brand, or collaborate.
