A Slack workspace is made up of channels, where team members can communicate and work together. When you join a workspace, you'll need to create a Slack account using your email address.
If you plan to join more than one workspace, you'll need to create a separate account for each one. You can join as many workspaces as you'd like, and there's no limit to the number of Slack accounts you can create with the same email address.
Ways to join a workspace:
Accept an email invitation from someone in the workspace
Join your company's workspace automatically using your work email address
Find workspaces you're eligible to join by looking up your email address
Check your mobile inbox for an email invitation from Slack.
Tap Join Now.
Enter your full name and tap Next.
Create a password and tap Next.
Sign up with your company email address
Some workspaces allow anyone with an email address on an approved domain (like @yourcompany.com) to join without first receiving an invitation. To join your company's workspace using your work email address, follow these steps:
Enter your email address. (We'll be sending you an email!)
On the same mobile device, locate and open your confirmation email from Slack. Tap Confirm Email Address to open the app, or tapSign in manually to enter your Slack URL and password.
From the list of workspaces you’re eligible to join, click Join workspace. If you’re joining a Slack Enterprise Grid organization, click Sign in.
Note: If no existing workspaces and no pending invitations are associated with this email, you can tap either Create a new Slack workspace or Try another email address.
