While managing notifications and information flow can sometimes be challenging in larger workspaces, the productivity and collaboration benefits far outweigh these limitations." Jun 11, 2026 AR Arthi R.EngineerAccounting, 1001-5000 employees "Its free plan has limited message history and integrations. While it’s great for real-time chat, Slack isn’t ideal for long-form discussions or detailed project management."
