Note: Set your Slack Connect discoverability preference or manage discoverability for your workspace if you're a Workspace Owner or Admin.


Search for people by email

  1. From your desktop, click  Slack Connect in your sidebar.
  2. Enter someone's email into the search field and press Enter
  3. Click their profile to see if they use Slack.
