What I will often do is batch email. Works. Until whatever it is reaches some critical point. Often nothing does.

SMS, or a call works then.

If those happen too much, I trigger a what is worth what discussion. Perhaps my point of focus needs to wait. And it can. No worries, but for the expectations associated with it will need to be managed along with that wait.

There is a cost to everything. Communicating that cost helps with this stuff. Can help very considerably.
