Slack Connect guide: work with external organizations
Rather than using email to communicate, you can use Slack Connect to work alongside people from external organizations in a Slack channel or direct message (DM). Read on for an overview of Slack Connect.
Slack Connect for channels
When you need to work as a group, you can use a Slack channel to host up to 250 organizations. Here's what to keep in mind:
- To work in channels together, each organization must be using a paid Slack plan.
- Like other channels in Slack, people can join the channel or be added to it by someone else from their organization.
- People from different organizations working together in channels can send each other DMs. To work in a group DM, everyone in the conversation must be in at least one channel together.
Tip: If you’d like to work with an organization that’s either not using Slack nor on a paid Slack plan, you can invite them to try Slack Connect for free.
Your organization owns any channels created in your workspace or Enterprise Grid org. When using Slack Connect, only the organization that owns a channel can do the following:
- Invite organizations
- Remove other organizations
- Manage posting permissions
- Continue using the channel if external organizations have been removed or disconnected
Using apps and workflows
When using apps and workflows in a channel with people outside your company, here’s what to expect:
- Workflows can be used by anyone in the channel.
- Shortcuts associated with apps are available to people from other organizations if an app is installed to their workspace. When people take an action from an app shortcut, it will only apply to the account they've connected to the app.
- Apps added by another organization will include that organization's Slack icon next to the app name. Only people from the organization that added an app can remove it from a channel.
- People in the channel can see messages from bots and apps. They can also exchange messages with an app’s bot user if it’s been added to the channel.
- Your organization’s custom apps and shortcuts can only be used by your organization, but messages posted by the app or shortcut can be seen by everyone in the channel.
Slack Connect for DMs
If you’d like to communicate one-on-one with someone from an external organization, you can use a DM. On any Slack plan, you can start a DM by sending someone an invitation, or accepting an invitation you've received.

Identify Slack Connect conversations
When you hover over a channel name or DM, you'll see if any external organizations are in the conversation. You'll also see a banner with the same information when you view the conversation. By default, all your Slack Connect channels and DMs will be organized into the Connections section in your sidebar.
Manage Slack Connect from your sidebar
Click Slack Connect at the top of your left sidebar to send and accept invitations, manage your invitations, and more. Depending on your role and permissions in Slack, you may find key actions to manage Slack Connect for your organization.
View member profiles
Organizations can choose what profile information other organizations can see: either just basic details, like names and profile photos, or additional details like statuses and timezones. Profile photos for external people will be marked with their organization’s Slack icon in the bottom-right corner.
Using custom emoji
You can use your organization's custom emoji like you would in any other channel or DM. External people can see your organization's custom emoji and add them to their organization so that they can use the same emoji too.
