For a user to participate in a Slack workspace, they need to be in the channels to participate in the discussion. These channels won’t necessarily be the same for everyone as everyone has different skill sets and interests. Nevertheless, you can configure some channels in the server as being the default.
Default channels are automatically joined by new user accounts, although new default channels are not retroactively joined automatically. Potential uses for default channels include a company/group-wide announcement channel, a news channel, a channel that provides the menu for the day at the building’s canteen. Or a channel hub that lists all channels to help users see what’s available.
How to Set up Slack Channels for Users to Join Automatically
To configure the default channels in your workspace, you need to browse to the workspace settings and permissions page. To get there, you first need to click on the workspace name in the top-right corner. Next, in the dropdown menu, select “Settings & administration.” Then go to “Workspace settings” to open the workspace settings in a new tab.

In the default “Settings” tab, click on the “Expand” button for the “Default channels” settings.

In the textbox, select one of the suggested channels or start typing to narrow down the results. You have to select channels that already exist; however, you do not need to select the “#general” channel. It is already always marked as default.
The “#general” channel is always joined by all users and can’t be left as it is also always marked as “required.”
Once you’ve edited the list of default channels to your preference, click “Save” to save and apply the changes.

By configuring Slack’s default channels, you can ensure that users are added to various channels by default. They join the workspace, which can offer useful information. By following the steps in this guide, you can configure the list of default channels in your workspace.
