Yes! Unlike email, Slack is not susceptible to spam or phishing, which causes 90% of data breaches. Your Slack handle cannot be sold to advertisers or put on a mailing list. You will only ever receive Slack messages from other people inside your organization, or from trusted partners using Slack Connect. You may get notifications from apps integrated with your workspace, such as Asana, Google Docs or Jira.

Slack offers enterprise-grade data protection and privacy. Granular controls allow admins to customize security for each user, so no one sees things they shouldn’t. Learn more about how Slack can securely replace email inside your company.

Channels are where work happens in Slack. A channel is a single place for a team to share messages, tools and files. People often create channels for company announcements, customer support triage, asking for IT or HR help, and sharing social interests.

Channels can be public (open to everyone at the organization) or private (invite-only). In addition, organizations on a paid Slack plan can share a channel with external partners like agencies, clients and vendors with Slack Connect. Learn more about how channels can speed up your daily work here.

Slack Connect is a more secure and productive way for organizations to communicate together. It lets you move all the conversations with your external partners, clients, vendors and others into Slack, replacing email and fostering collaboration. Slack’s enterprise-grade security features and compliance standards, like Enterprise Key Management, extend to Slack Connect. Learn more about Slack Connect here.

Excellent question. Slack is a new way for your entire company to communicate. It replaces email with something faster, better organized and more secure. Instead of one-off email chains, all your communication is organized into channels that are easy to create, join and search. When there’s a channel for everything going on at your company, everyone knows exactly where to go to get work done.
