UnInbox is an open-source communication hub that gives modern teams shared email inboxes and messaging in one place. It is built for sales and support conversations, with AI features that can be switched off, and it runs fully standalone or alongside an existing Google setup. Hosted team and enterprise plans come with a free @uninbox.me address and custom domains, while the Nuxt 3 monorepo can be self-hosted. It suits teams that want a shared, controllable home for email without relying on a closed provider.[1][2][3]
Quick verdict
Sales and support teams that share email inboxes benefit most from UnInbox. Its shared team inboxes, optional AI features, and choice of hosted plans or self-hosting suit organisations that want control over team mail. Pricing is not published and email setup needs manual work, so cost-driven individuals and teams wanting one-click hosting should look elsewhere. If you want an open-source team email hub you can host yourself, choose UnInbox; if you want managed AI triage inside Gmail, consider an assistant layer instead.[1][2][3]
What UnInbox does for team email
Shared team inboxes Conversations live in shared inboxes so sales and support teams can manage mail together instead of forwarding threads.[1][2]
Sales and support modules Dedicated modules cover the sales and support workflows the product is positioned for.[1]
AI features you can switch off AI capabilities are optional and can be disabled, which suits privacy-conscious teams.[1]
Standalone or alongside Google UnInbox can replace existing mail handling entirely or run next to a current Google setup.[1]
Free @uninbox.me address Hosted users get a free @uninbox.me address to start sending and receiving immediately.[1]
Custom domains on hosted plans Teams can use their own domains on the hosted offering instead of the default address.[1]
Security-first design The project describes a security-first approach to team communication infrastructure.[1]
Team and enterprise editions The offering is split into team and enterprise editions, with a sales contact for the latter.[1]
Who will love it
Sales teams sharing one inbox Teams that answer sales mail together get a shared, organised home for those conversations.[1][2]
Support teams wanting control Support teams that want their mail on infrastructure they can host and inspect suit the open-source model.[1][2]
Privacy-minded teams Teams that want AI assistance available but off by default suit the togglable AI design.[1]
Who should avoid it
Individuals wanting personal email The product is built for teams, so solo users wanting a simple personal mailbox should look elsewhere.[1][2]
Teams needing confirmed SSO or API No public SSO or API documentation was found, so teams that require either should verify first.[1][2]
Teams wanting one-click email setup Self-hosting needs manual email configuration with no one-click flow, so teams without operations help should prefer hosted plans.[1]
Compatibility and setup
Web application UnInbox is a Nuxt web application; no desktop or mobile apps were documented.[1][2]
Docker-based self-hosting Local development and self-hosting use pnpm with docker:up and db:push, but email configuration stays manual.[1][2]
AGPL-3.0 with commercial ee terms Non-ee code is under AGPL-3.0 while the ee directory carries a separate commercial license, so commercial self-hosters should review both.[1]
Questions worth asking

How much does UnInbox cost per month?
Does UnInbox work with Gmail or Google?
