## What it is
UnInbox is an open-source collaborative email platform for teams and professionals, offering shared inboxes, unlimited addresses, conversation notes, and workflow statuses. It is a self-hostable alternative to hey.com, front.com, and missiveapp.com, built with Next.js, React, and Hono.

## Use cases
- manage shared team inboxes like support@ and sales@
- replace hey.com or front.com with a self-hosted email tool
- collaborate on email conversations with notes and assignees
- track email workflows with statuses
- create unlimited email addresses for a business
- host my own modern email client

## When to choose
- your team handles email collaboratively and needs shared inboxes
- you want a self-hosted, open-source alternative to hey.com or front.com
- you need unlimited email addresses with per-email workflows

## When to avoid
