Invite new members to your workspace

There are a few ways to give new people access to join your workspace:

  • Email an invitation to one person or several people at once
  • Share a custom invite link to your workspace
  • Allow people to sign up using their email address

Who can send invitations?

Workspace Owners and Admins can invite new people to their workspace, and they can allow their members (excluding guests) to send invitations as well. 

On the Free plan, members are able to send invitations by default. On paid plans, this permission must be enabled by a Workspace Owner or Admin. If you're an Owner or Admin, learn more about changing invitation permissions.

Share an invite link 

Workspace Owners and Admins can create a unique link to share that anyone can use to join the workspace. Once created, anyone who can send invitations can view and share the link. Use the steps below to create one:

  1. From your desktop, click your workspace name in the top left.
  2. Select Invite People from the menu.
  3. Select Members
  4. Click Get an invite link to share.
  5. From the drop down menu, choose when you want your link to expire.
  6. Click Create Invite Link.
  7. Click Copy and share the link with your future members! 


Allow email signup

Workspace Owners can allow email signup. This allows people with an email address from a specific domain (e.g., your company's domain) to join a workspace without an invitation.

Before joining a workspace, we'll send a validation link to each new member's email address to verify their identity. Only those with an address at the workspace's specified domains can create an account.

Tip: Workspace Owners! Learn how to adjust your workspace signup mode.

 

Manage pending invitations

On desktop, Workspace Owners and Admins can view your workspace’s pending and accepted invitations and make changes, if necessary.

Choose Revoke Invitation to remove it from your list and prevent any delivered invitations from being used. Or select Resend Invitation to deliver a fresh email invitation to the person’s inbox, in case it expired or was lost.

Here's how to see who has and hasn't accepted your invitation, and either revoke or resend an invite:

  1. From your desktop, click your workspace name in the top left.
  2. Select Invite people from the menu.
  3. Click See pending and accepted invites for your workspace.
  4. On the Pending Invitations tab, click the  right arrow icon next to the invitation you want to view.
  5. Click Revoke Invitation, Resend Invitation, or do nothing by closing the browser.


Invitation limits

You can send invitations to as many people as you’d like. Slack may limit the option to send more invitations if you've already sent a large number, and few have been accepted. If you hit the invitation limit, any pending invites you've already sent are still valid, you just won't have the option to send more.

You can avoid hitting the limit by only sending invitations to people who have asked or who are approved to join your workspace. If you've reached a limit while trying to invite a large group of coworkers, please contact us.

Note: Revoking invitations will not lift the limit — it is based on the acceptance rate of invitations that have already been sent. 

Who can use this feature?
  • Workspace Owners and Admins can use this feature, and sometimes members.
  • Available on free and paid plans.
