Email, Slack, MS Teams are overwhelming, any recommended ways to manage your day/team better?

Hi All, We are building Sparrow (https://www.mysparrow.io/) to help remote hybrid cross-functional teams function asynchronously by moving trackable actions out of communication tools and driving accountability. I am trying to catalogue everything (tools, best practices, methods) that people currently use to manage the chaos from the high volume of Slack messages/ emails. please share any thoughts you may have, will massive help our understanding of this problem space.
