UnInbox

Meet UnInbox

UnInbox is an open-source email workspace for teams that need to coordinate conversations. Shared spaces let people discuss an email internally and reply from a shared address, reducing the need to forward messages between colleagues. Workflow statuses show whether a conversation still needs attention or has been handled.

Teams can create multiple addresses for different functions and use custom domains on supported plans. Conversation assignments help make ownership clear, while personal spaces support individual work alongside shared inboxes. SMTP and API access are available for integrations. The service offers hosted plans with different collaboration and retention options, including dedicated instances for larger organizations.
