Slack helps us keep the conversation focused and avoid multiple threads that create more confusion. I would say that has been the biggest advantage for us.
Slack enhances productivity by organizing messages, integrating with apps for real-time updates, and offering intuitive design with minimal training needs. Features like communication channels are valued, yet lacking are video conferencing, consistent mobile notifications, and robust document collaboration. Users appreciate customization but face issues integrating with Gmail, Outlook, and CRMs. Slack should improve stability and support for large-scale operations to meet tech buyers' needs better.
