Invite new members to your workspace

A Slack workspace is made up of channels where people can communicate and work together. Whether your Slack workspace is brand new or it's been around for a while, read on to learn how to invite your teammates to Slack.

Tip: If you're looking to add someone to a channel in your workspace, find out how in Add people to a channel.


Workspace invitation permissions

Your ability to invite other people to your workspace depends on your role in Slack and your workspace settings:

Note: Workspace owners can approve certain email domains so that anyone with an approved email can join their workspace automatically.

Members who don't have permission to send invitations can request them instead. When invitation requests are approved or denied, members will receive a message from Slackbot to let them know.

Sharing an invitation link

Members with permission to send invitations can create a link that anyone can use to join a workspace. Invite links can be used by up to 2,000 people. If you reach this limit, you’ll need to create a new link.

Desktop

iOS

Android

  1. From your desktop, click on your workspace name in the top left.
  2. Select Invite people to [workspace name] from the menu.
  3. Click  Copy invite link
  4. If you like, click Edit link settings to choose an expiration date and decide if you’ll receive notifications from Slackbot when someone uses your link.

  2. From the  Home tab, swipe right to open the main menu. 
  3. Tap  Invite people
  4. Tap  Create an Invite Link
  5. Choose an expiry date. 
  6. Tap Copy link or Share link, then send the link to anyone that you want to invite.
It's not possible to create invitation links on the Android app at the moment.

Note: You won’t see the option to create an invitation link if single sign-on (SSO) has been enabled for your workspace. If SSO is not enabled and you can't see this option, find an owner or admin to ask for help. 

 

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 invitations will not lift an invitation limit.

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

Who can use this feature?
  • Workspace owners, workspace admins and members (by default)
  • Free, Standard, Plus and Enterprise Grid subscriptions
