If you think email is starting to feel outdated, perhaps it's not the tool, but your misuse of the tool. For years, I resorted to email when other forms of communication would have been much more effective. Why? Because everyone has an inbox. It's the most reliable way to reach someone without having to know all their different communication preferences. What our chosen email tool did was help break us out of the email box we were in to see all the different communication streams we could choose from for any given task.
