Slack is the most popular SaaS platform, dominating the internal communications space. The company has taken a holistic approach to its overall user experience and has created a product that delivers notifications that fit seamlessly into our lives. Slack's preferences give us so much control over what we receive and when, even if we have it open in the background, we won’t be constantly disrupted by alerts throughout our entire day. Slack is one app that does this extremely well and PMs can learn a lot from its many integrations and malleable notification preferences.
