Missive

Missive provides a shared inbox environment that lets teams handle email without altering their existing workflow. Users can view ongoing conversations, assign internal statuses, and add comments directly on messages, making it clear who is responsible for each item. The platform also supports turning any email into a task and displays each person’s workload for today, tomorrow, and the coming week.

Team spaces are configurable so each group can have its own inbox, task list, and discussion area. Tags and filters help surface messages that require attention from multiple members, while automation rules automate repetitive actions. Integrations with more than twenty‑five external applications bring additional context into the email view.

The service is aimed at small‑business teams that rely heavily on email for coordination and need a way to collaborate on messages, track responsibilities, and customize the interface to match their processes. It runs on macOS and is considered stable.
