This has crept into schools as well. At many (most?) preschools around here have apps to document the kids' day, they send out almost daily emails and reminders about various things. If you have kids at preschool, regular school and after-school centers you're getting a constant deluge of information. Add to it that they all have different apps that don't work well (schedule, attendance etc), so of course they use email in addition.

I love our current preschool precisely because they use very little technology: we actually talk to the teachers during drop-off and pick-up if needed, and get maybe one email a month. Their expressed philosphy is to be "present" with the kids and spend as little time as possible on other (administrative) things.
