Internal chat

In Missive, everything external is email, everything internal is chat—and both live together in unified conversations. No more switching between your email client and a separate chat app to collaborate with your team.

When to use internal chat

Internal chats are useful in many situations:

• External communication: Discuss messages received from outside the company (email, SMS, social media, etc.)

• Ask for help: Need guidance on how to respond? @mention a colleague directly in the email thread

• Share context: Provide background information before someone else replies

• Express opinions: Discuss ideas before taking action

Instead of forwarding an email or calling a manager, @mention someone and ask for help directly in the thread. They can access the full context instantly and guide you through the chat.

Types of chat conversations

Chat in any conversation

Every conversation has a chat box where you can talk with teammates. These internal chats are never seen by external recipients.

To start collaborating:

1. Open any conversation

2. Type in the chat box at the bottom

3. Use @username to mention specific people

You can also click New conversation from the + menu to start a chat-only conversation with your team, or as notes for yourself.

Team chat rooms

Teams can have dedicated chat rooms where all members can discuss together. Team rooms are automatically created when you configure a team with this option enabled.

Team chat rooms make it easy to @team several people at once. Each team can also have a dedicated team inbox where messages from shared accounts are directed.

Teams can represent anything:

• A function or role: Support, Sales, Marketing

• A client group: Delta Materials, Disney

• A project: Construction Site ABC, Spring 2026 Campaign

• A social space: General room, Random Facts channel

To configure team chat rooms:

1. Go to Settings > Teams

2. Select your team and click Edit

3. Enable or disable Chat room

Organization room

Missive automatically creates a general chat room for your organization where all members can connect and engage beyond emails.

1-1 room

Missive also creates private 1-1 rooms between each team member. Start a conversation by clicking on a coworker's avatar in the sidebar or using the command bar.

Creating a chat room

Missive is flexible with internal chats. A chat can be short-lived for a single discussion, or long-lived for an ongoing project.

1. Click the + button, then New conversation

New conversation creates a conversation that behaves like email conversations: it can be labeled, archived, snoozed, assigned, etc.

1. Pick a title, choose who should have access, and start chatting

1. Optionally, customize the icon by prepending an emoji to the conversation title

Pin to sidebar

Pinned conversations stay right where you put them in your sidebar—unlike your Inbox where new conversations push older ones down. Use Pin to sidebar to keep important chat rooms easily accessible.

Create custom sections in your sidebar to group pinned items however you like.
