We do three things: First, we use Missive to integrate email and chat. This way everything's in one place, properly threaded, and we can easily discuss emails internally in context. Much much better than GMail + Slack. Second, I run video chat office hours twice a week (Tuesday/Thursday). Anybody can drop in to discuss anything — or not, if there's no need. This lowers the activation energy for "in person" discussions that otherwise might not get scheduled and promotes async work the rest of the time. Third, regular company offsites! Even a few days a year is good.
