It's absurd to expect people to adjust their communication timing based on each contact's preferences, when the recipient can simply adjust their communication devices to block and filter messages/calls according to their preferences. That way each person only has to do the work once, compared to having to remember each of maybe dozens or hundreds of people's preferences.

Further, my team’s mail list spans people working from IST through PT (13.5 hours). If everyone works a local 9-5*, there is no moment when mail to that list (or a post to our slack channel) won’t hit someone “off hours”.

* Or anything even close to that…

Throttle on input.
