About

Overview

Slack is a channel-based messaging platform designed for team collaboration. It replaces internal emails by organizing conversations into channels, allowing teams to share files, integrate with thousands of external tools, and stay aligned in real-time.

Pricing & Free Tier

Free Tier: Yes. Includes unlimited users, 1-on-1 audio/video, and 90 days of message history.
Pro: $8.75/user/month (billed annually). Unlocks unlimited message history and unlimited app integrations.
Business+: $15/user/month. Adds SSO and advanced compliance.

How to Use

Create a workspace at slack.com and invite your team.
Create channels for different projects (e.g., #marketing, #dev).
Use @ to tag a colleague, or click the "+" next to the message box to attach files.
Click the "Huddles" icon in any channel to start a quick audio or video call.

Important Notes

Message Limits: On the free plan, messages older than 90 days become hidden and inaccessible. You must upgrade to keep them.
Notification Overload: Be sure to configure your notification preferences; otherwise, Slack can become a massive distraction.
