Manage channel posting permissions

Channel members can limit who can post to the channel they’re in, making it read-only for everyone else. This helps large announcement channels stay on topic and free from distraction.

 Channel posting permissions by plan 

  • Free and Standard subscriptions
    Posting permissions can only be set for the #general channel. By default, anyone can manage this channel's posting permissions, unless restricted by a Workspace Owner or Admin.
  • Plus subscription
    Posting permissions can be set for any channel, except for channels that are shared with an external organisation. Anyone on the workspace can manage a channel’s setting.
  • Enterprise Grid subscription
    Posting permissions can be set for any channel, except for channels that are shared with an external organisation. By default, anyone can manage a channel's posting permissions, unless restricted by administrators.

Note: Only org owners and admins on the Enterprise Grid subscription have channel posting permissions for multi-workspace channels by default.


Set channel posting permissions

First of all, review the channel posting permissions by subscription above to see if you have access to this setting. Once someone sets posting permissions for a channel, only that person, an owner or an admin can override that setting.

  1. Open a channel.
  2. Click the  cog icon to open the Channel settings menu.
  3. Click Manage posting permissions
  4. Choose who can post in the channel and if you want to allow message threads.

Note: Workspace owners and admins always have channel posting permissions, unless they’re in multi-workspace channels.
