How to let users with my domain automatically join my organization?

Auto-join allows new users who sign up with the same email domain as your organization (e.g., @yourcompany.com) to automatically join a specific workspace - without needing a manual invitation. This is useful for onboarding team members quickly and reducing manual user management.

Before you start

Make sure the following requirements are met:

Plan requirement: Auto-join is available on the Business plan only. It is not available on Free, Starter, Active, Pro, trial, or legacy plans.

Role requirement: Only the Organization Owner can configure auto-join settings. Admins, Users, and Guests cannot access this setting.

Domain requirement: Auto-join works only with non-public email domains (e.g., @yourcompany.com). Public domains like @gmail.com, @yahoo.com, or @outlook.com are not eligible.

How auto-join works

When auto-join is enabled and a new user signs up for Coupler.io with an email address that matches your organization's domain, they are automatically added to the selected workspace. No invitation is needed - the user simply registers and gets access.

For example, if your organization's domain is yourcompany.com  and auto-join is configured for the "Marketing" workspace, any new user who signs up with an @yourcompany.com email will be automatically added to the "Marketing" workspace.

How to enable auto-join

1. Go to Organization Settings. You can access it from the left sidebar menu.

2. Open the Settings tab.

   Note: This tab is visible only to Organization Owners. Other roles cannot access it.

3. Find the Auto-join toggle.
4. Turn the toggle On.
5. Select a workspace from the dropdown menu. This is the workspace that new users with a matching email domain will automatically join.
6. The setting is saved automatically once you select a workspace.

Important: If you turn the toggle on but don't select a workspace from the dropdown, the setting will not persist. If you navigate away or refresh the page, the toggle will revert to Off. You must select a workspace for auto-join to be active.

How to change the auto-join workspace

1. Go to Organization Settings → Settings tab.
2. Open the workspace dropdown under the auto-join toggle.
3. Select a different workspace.

The change takes effect immediately. New users who sign up with a matching domain will now be added to the newly selected workspace instead.

Note: Changing the auto-join workspace does not affect users who have already joined. They will remain in the workspace they were originally added to.

How to disable auto-join

1. Go to Organization Settings → Settings tab.
2. Turn the auto-join toggle Off.

New users with a matching email domain will no longer be automatically added to any workspace. They will need to be manually invited.

Note: Disabling auto-join does not remove existing users from the workspace. It only stops new automatic additions.

FAQ

Which role do auto-joined users get? Users who join via auto-join are added with the User role at the workspace level.

Can I set auto-join for multiple workspaces at the same time? No. Auto-join can be configured for one workspace at a time. If you need users to access multiple workspaces, you'll need to invite them manually to additional workspaces.

Does auto-join work for existing Coupler.io users? Auto-join applies when a new user signs up for Coupler.io. If someone already has a Coupler.io account, they will need to be invited to your workspace manually.

What happens to auto-join when I downgrade my plan? If you downgrade from Business to a plan that doesn't support auto-join, the feature will be disabled. New users will no longer be added automatically. Existing users who previously joined via auto-join will not be affected.

Can I use auto-join together with manual invitations? Yes. Auto-join and manual invitations work independently. You can have auto-join enabled for one workspace while still inviting users to any workspace manually.
