Join a Slack workspace

In order to be a member of an existing Slack workspace, you'll have to join one first. There’s no limit to the number of workspaces you can join — and you can even use the same email address.

Tip: Need to create a new workspace? Read Create a Slack workspace.

There are a few different ways to join a Slack workspace:

💌   Accept an email invitation

A member or admin of the workspace can send you an email invitation. Once you’ve been invited to join, the first step is setting up your Slack account. Scroll down for more on accepting an invitation with Slack for desktop and mobile.

Does your company use single sign-on? If so, we’ll already have the info they provide, like your name and email address. All you’ll need to do is authenticate your account with your identity provider (like Okta, OneLogin, G Suite, and so on!)

💻   Join with an approved email address

Depending on the workspace signup mode, you may be able to create an account with an email address in an approved domain, like @yourcompany.com.

To join a workspace this way, you’ll need to know its Slack URL — it would look something like acme.slack.com. Visit your Slack URL, then click create an account. We’ll guide you through the rest.

🔎   Find your workspaces

If you think you’re eligible to join a workspace, but haven’t received an email invitation, we can look up which workspaces you’re able to join based on your email address. Read more at Find your Slack URL.
