Invite new members to your workspace

Whether your Slack workspace is brand new or it's been around for a while, this article will explain how to invite others to join.

💡Need to add someone to a channel rather than a workspace? Learn how in Add people to a channel.

Tip: If you're an Enterprise Grid org owner or org admin, follow the steps in Add members to workspaces on Enterprise Grid.

 

Workspace invitation permissions

Your ability to invite others to your workspace depends on both your role in Slack and your workspace settings.

  • Workspace owners and workspace admins can invite both members and guests. Please note that guests can only be invited to workspaces on paid subscriptions.
  • Members can invite other members if an owner or admin enables this option. Otherwise, they can request invitations for members or guests for admins to approve.
  • Guests cannot send or request invitations.

Allow email sign-up

Workspace owners can enable email sign-up to allow people with an email address from a specific domain (e.g. your company's domain) to join your workspace without an invitation. Before someone can join a workspace this way, Slack will send a validation link to their email address to verify their identity.

  1. From your desktop, click your workspace name in the top left.
  2. Select Settings & administration from the menu, then click Workspace settings.
  3. Next to Joining this workspace, click Expand.
  4. Choose Allow invitations and approve invitations for any email address from these domains.
  5. Enter your domain(s), then click Save.

Tip: If a member requests an invitation for someone with an email address on an approved domain, an invitation will be sent automatically.


Manage pending invitations

Workspace owners and admins can view pending and accepted invitations and make either of the following changes:

  • Revoke invitation
    Revoke an invitation to prevent an invited member from using it or disable email notifications that they may receive from Slack before accepting
  • Resend invitation
    Send a new email invitation if the original has expired or been lost
  1. From your desktop, click your workspace name in the top left.
  2. Select Invite people to [workspace name] from the menu.
  3. Click See past invites.
  4. Click the Pending tab at the top of the page. 
  5. Next to the invitation you want to manage, click Resend Invitation or Revoke.

Tip: Members with permission to send workspace invites are not able to resend pending invitations. Contact a workspace owner or admin to resend them on your behalf.

Note: After you revoke a pending invitation, the invited member's account will show up as deactivated. To re-invite them, you'll need to activate their account from the Manage members page, then select Resend invitation.

 

Invitation limits

In certain circumstances, Slack may limit your ability to send invitations. This typically happens if you’ve sent many invites, but few have been accepted.

If you hit an invite limit, all of your pending invitations will remain valid. Please note that revoking pending invites will not lift an invitation limit.

To avoid hitting an invite limit, create a shared invite link (or ask your workspace owner or admin to do so). Then, share it with anyone that you want to join your workspace.
