Organize your work

Channels bring order and clarity to work — you can create them for every project, topic, or team. When there’s a channel for everything, you can focus on the conversations and work that matters most to you.

Create alignment

Channels provide you and your team with a shared view into the work being done. With access to the same information, everyone in the channel can work in sync, and new members have full context when they join. And whenever you want to talk, simply use Slack Huddles to start a live voice conversation.

Be more productive

As you work in channels, your conversations and files become a searchable archive that gets more useful with time. Find answers, get context and make better decisions without having to chase down people or information.

Work together in dedicated spaces

Channels are flexible spaces for all the people, tools and files you need to get work done—no matter how you work.

Public channels

These channels are open for anyone at your company to join or find in search. Increase transparency while allowing everyone to benefit from the context of your conversations.

Private channels

For sensitive or confidential conversations, you can use private channels. Only those who are invited can view the channel or find its contents in search.

Slack Connect

Bring people from external organizations into secure Slack channels. Speed up communication and get work done with clients, vendors, agencies and more.

You can invite someone outside of your company to share a channel in Slack. Or, skip the channels for now and send an invitation to start exchanging direct messages — just like you would in other DMs!

It really only takes a few clicks to start working closely with vendors, customers, and more. Our sales team is happy to help you get started.

Channels work best—and help you work better—when your organization follows a few basic guidelines around them:

• Consider turning group chats into channels to make conversations easier to find and reference
• Have a consistent naming convention across your organization’s channels, so everyone can quickly identify which channel has what they need
• Ensure that every channel has a clear purpose for why it was created, and include that purpose in the channel description
• Update every channel topic to include a clear summary of what everyone is currently working on
• Set up new channels by adding relevant information into the channel’s canvas, uploading any important project files, and posting a welcome message to kick things off
• Add handy reference links into the channel’s bookmarks bar for easy access, or pin key messages, too
• Add the right people to your channel (including everybody involved in the project or topic) so they can all work together, all from one place

You sure can! With Slack Connect, you can invite people outside of your company to share any existing channel in your workspace or create a new channel if you want to start fresh.

Group chats are private between you and the recipient. Think of it as a private conversation two people might have in a small room.

With channels, you can assemble the right people in one space and organize around a common goal. Channels can be made public or private, and any member that’s added to a channel can easily read up on the past messages they need to get up to speed.
