With Slack you can: Organize your team conversations in open channels. Make a channel for a project, a topic, a team, or anything—everyone has a transparent view of all that’s going on. For sensitive information, create private channels and invite a few team members. No one else can see or join your private channels. To reach a colleague directly, send them a Direct Message. It’s completely private and secure. Drag, drop, and share your files. Not just your messages, but all your files, images, PDFs, documents, and spreadsheets can be dropped right into Slack and shared with anyone you want. Add comments, star for later reference, and it’s all completely searchable. If you use any services like Google Drive, Dropbox, or Box, just paste the link and that document is immediately in sync and searchable too. Reclaim your workday. Less email. More productive. Our customers see an average 48.6% reduction in internal email, helping them enjoy a simpler, more pleasant, and more productive work life.
