Missive

Missive is a collaborative team-inbox and communication app that brings shared email, team chat, and task management into one workspace. Teams manage shared inboxes (like support@, sales@, or info@) together — assigning conversations, adding internal comments right beside the email, and avoiding duplicate replies — while also chatting and collaborating in the same tool. By blending external communication (email, SMS, WhatsApp, social) with internal chat around each conversation, Missive lets teams handle customer and business communication collaboratively without switching between an email client and a separate chat app.

The platform is built for shared, accountable communication. Shared inboxes with assignments, internal threads/comments, and collision awareness keep teams coordinated; rules and automations route and label conversations; and canned responses, scheduling, and analytics speed handling. Missive supports multiple channels (email, SMS, WhatsApp, Messenger, Instagram, and more), integrations with CRMs and other tools, and an API. It sits between a personal email client, a help desk, and a chat app — appealing to small teams and businesses that want to collaborate on email and messages without a heavyweight support platform.

Missive serves small teams, agencies, and businesses that collaborate on shared inboxes and customer communication. It offers a Free plan (up to 3 users, 15 days of email history), a Starter plan around $14 per user/month (billed yearly), a Productive plan around $24 per user/month (integrations, rules and automations, analytics, API), and a Business plan around $36 per user/month (SAML/SSO, IP restriction, advanced analytics), with a 30-day trial. It competes with Front, Help Scout, Hiver, and Twist, differentiating on blending shared email, chat, and tasks in one collaborative inbox.
