Missive

Missive is a collaborative inbox app that brings team email, group chat and shared communication channels together in one place, so teams can manage all their conversations collaboratively rather than in isolated personal inboxes. It targets a common but painful problem: shared addresses like support@, sales@ or info@ that multiple people need to handle, where email alone leads to confusion, duplicated replies and a lack of visibility. Missive turns those shared inboxes into a coordinated, transparent team workflow.

The core experience combines email with built-in team chat and collaboration. Team members can discuss an email internally right alongside it — without messy forwarding or separate Slack threads — assign conversations to the right person, leave internal comments, and even draft replies together. This means everyone has context, nothing falls through the cracks, and customers or contacts receive coherent, well-coordinated responses. It effectively merges the immediacy of chat with the structure of email into a single, shared workspace.

Missive supports multiple shared and personal inboxes, rules and automation to route and organize messages, integrations with other tools, and additional channels beyond email so teams can manage communication across platforms in one interface. This versatility makes it useful for customer support, sales, operations and any small-to-medium team that handles shared communication and wants to do it together rather than in silos. Its clean design and thoughtful collaboration features have earned it a loyal following among teams that find dedicated help desks too heavy but personal email too limiting. For organizations looking for a collaborative middle ground — a shared inbox where the whole team can communicate, coordinate and respond as one — Missive offers an elegant, practical and genuinely team-oriented solution.
