UnInbox | Collaborative Email to get shit done.
Shared inboxes, infinite addresses, and per email workflows.
What it is
UnInbox is a collaborative email platform designed for teams and modern businesses seeking to manage shared communications more effectively. It replaces traditional email forwarding and reply-all chains with structured workflows. The service is built for teams that handle emails from multiple shared addresses like support, sales, or info, and it is open-source.
Main Features
Shared Inboxes & Organization
- Shared Spaces: Allows teams to collaborate on email conversations, comment internally, and reply from shared addresses without using FWD: or RE: RE: RE:.
- Infinite Email Addresses: Supports the creation of unlimited aliases (e.g., admin@, support@, sales@, accounts@) for different functions.
Workflow & Tracking
- Workflow Statuses: Enables teams to track the status of each email conversation to ensure tasks are completed and avoid duplicate efforts.
- Convo Assignees: Allows specific team members to be assigned to conversations for clear ownership.
Technical & Administrative
- Custom Domains: Supports unlimited custom domains on paid plans.
- SMTP & API Access: Provides programmatic access for integration and automation (available on Pro plan and above).
- Dedicated Instance: Offers a privately hosted instance for Enterprise customers.
- SAML SSO: Supports enterprise-grade single sign-on for security.
How it works
Team-Based Customer Support
A support team uses a shared space for support@company.com. Incoming customer queries are visible to the entire team. Agents can add internal comments to discuss solutions before sending a unified reply from the shared address. Workflow statuses (e.g., Open, In Progress, Resolved) are used to track which emails have been handled.
Multi-Department Email Management
A company creates separate addresses like sales@, billing@, and careers@. Each address is routed to its own dedicated space. The sales team collaborates on leads in one space, while the HR team manages job inquiries in another, all within the same UnInbox organization.
