Essential for remote teams – reduced email by 70%
We’ve been using Slack for 3 years across a fully remote engineering team of 85 people. It has fundamentally changed how we communicate – our internal email volume dropped 70% within the first month.
The channel organization keeps conversations focused and searchable. We have channels for each engineering team, project-specific channels that auto-archive after completion, and social channels that build culture across time zones. The search functionality is powerful enough that I can find discussions from months ago within seconds.
Integration with our development tools is seamless. GitHub notifications, CI/CD alerts, and monitoring alerts all flow into relevant channels. Our incident response time improved significantly because the right people are notified immediately in Slack rather than checking email.
Slack Connect has been valuable for collaborating with external partners and agencies. We can work with vendors in dedicated channels without giving them access to our internal workspace. Security controls ensure sensitive channels remain internal-only.
