Collaborative inbox and email management for teams
Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.

AI-first email that turns your inbox into a chat-like workspace
AI snapshots unread mail and long conversations so you can catch up in seconds, while priority inbox surfaces the messages that matter first.
Draft quick replies, contextual responses, and brainstormed messages with AI assistance directly inside the composer.
Threads are grouped by person like a messenger app, and every connected account lands in one inbox with file management and powerful search.
Shared inboxes, channels and groups, collaborative docs and notes, tasks, and one-click audio and video meetings all live inside your mail workspace.
