At Automattic we have not been using email for the past dozen years for internal communications. We replace email with WordPress.com/P2 plus IRC (moved on to Slack).<p>In our internal P2s we count 1 million posts (that might have been emails), 2.6 million comments (that might have been email replies) across 1,100 P2s (that might have been email silos).<p>We are active on Slack, but decisions are made on asynch P2s which are the source of truth.
