Overview

Missive

Missive is a collaborative email and chat platform designed to help your team manage communication without jumping between different apps. You can manage shared inboxes for email, SMS, WhatsApp, and social media while chatting with teammates right inside the same interface. This eliminates the need for internal forward chains and BCCs, as you can discuss specific messages in side-chats and co-author replies in real-time.

The software is built for teams of all sizes, from small startups to large support organizations, who need to coordinate on high volumes of external communication. You can automate your workflows with rules, use canned responses for faster replies, and integrate your favorite CRM or project management tools directly into your inbox to keep your data synchronized.

The platform is built for modern teams who need more than just a dialer.

It integrates directly with your existing tech stack, ensuring your communication data stays synced with your CRM and productivity tools.
