Overview
Slack is the dominant team messaging platform for agencies, remote teams, and growing businesses. Channels keep conversations organized by project or topic; direct messages handle 1:1 and small-group communication. The free plan covers core messaging but limits message history to 90 days. Paid plans unlock full search history, group video calls, and advanced security controls.
