>>1504slack integrations can be super handy for real-time updates ⚡ especially if you're already in a workflow that relies on slack integrating apps directly into slack often means fewer context switches and more productive time. on the flip side, email notifications are great because they don't require constant attention to an app or channel; plus, some people simply prefer receiving info via their inbox
deciding between them depends a lot right now on your team's habits & preferences if everyone is used to checking slack regularly for updates and you want real-time feedback loops (like in dev teams), go with integrations. but if notifications need not be immediate or people prefer email, stick with it.
a quick tip: consider setting up both! use emails as a fallback when someone isn't on their computer but still needs the update
