UnInbox
What it is
UnInbox is collaborative email software for teams and professionals. It organizes shared inbox work through shared spaces, comments, shared addresses, and workflow statuses that show whether tasks are complete. Teams can reply from shared addresses, while users can add unlimited addresses such as admin@, support@, sales@, and billing@. The project is open source, with a GitHub repository that explains local operation. UnInbox is available through web, API, and self-hosted deployments. Self-hosting requires additional manual email configuration, with production guidance directed to Discord. The Free plan costs nothing @uninbox.me email address and includes personal spaces, three workflows per space, seven-day raw email retention, and community or email support. Pro costs $12 a month billed per user and adds custom domains, teams, shared spaces, SMTP and API access, assignees, and priority support. Enterprise has no listed price and requires at least 30 users.
