Does a zero email workplace reduce work?

Many teams wisely end the many downsides of email as they seek a culture of greater collaboration and transparency. They now use apps like Slack and Trello and get as many notifications a day as they used to get emails. The difference in functionality is profound. Now people can see what others are up to and this opens the door for more collaboration, alignment and being in sync together that email effectively prevents. At the end of the day, more value is delivered and people feel more connected.
