I generally agree with greg, and that covers 90% of the cases, for the times where Email is used with external entities, it usually gets dumped into issue tracking / wiki Most work communication is usually within our issue tracking system We use slack very lightly, - most of our conversations are face to face but anumber of remote employees, and slack is used instead of face to face. Often for video calls - copy pasting things to other people - a sort of mini internal HN where links are posted to interesting things in the dev world and we discuss - prodding people "Oi, my PR is still waiting .... " "did you setup ... ?" etc - telling people where we went to lunch so they can find us.
