By default, members’ email addresses are displayed in their Slack profiles, which are visible to their organisation and any external organisations that they work with in Slack Connect. If they’d like, owners and admins can adjust this setting to display email addresses only to members of their organisation, or to no one at all.
Display or hide email addresses
When email addresses are displayed in Slack profiles, members can use them to search for people that they work with. If email addresses are hidden, they still may be accessible through apps, test tokens or the API.
