I'm American. I check email once a day, max. Sometimes I'll just skip it all together. If stuff starts going sideways, I'll hear about it anyway. Most in my org sit in meetings half-listening while replying to emails or looking at their laptop/phone. I stopped carrying my laptop to meetings and only use pen/paper. Really helps with both my clarity of situation being discussed, and being more sensitive to noticing when I'm not adding value.

I encourage my team to limit email to once a day, as well as to decline meeting invites without a clear agenda or that don't state why they're needed.

This, parent comment is literally about nagging people.
