What it is
UnInbox is collaborative email software for teams and professionals. It provides shared inboxes, shared spaces, and workflow statuses so teammates can comment on conversations, reply from shared addresses, and see whether work is complete. Users can add unlimited addresses, including admin@, support@, sales@, and billing@ examples. The codebase is open source, with instructions for running it locally; self-hosting requires additional manual email configuration and production guidance through Discord. A 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, adding teams, unlimited custom domains, shared and public spaces, SMTP and API access, assignees, and priority support. Enterprise has no listed price, requires 30 users, and adds dedicated infrastructure, SAML SSO, long retention, onboarding, and organization-wide video support.
