This tends to run into problems with people not actually reading their email, especially when the messages are falsely classified as spam. That might not be a problem if all the members are on the same school mail server but it's problematic for general usage.
replyMany people don't read their email anymore. When I send an email I often have to send a text message to the person telling them I sent an email or they won't see it.

replyI don't see how that would work as in many jurisdictions, email is an accepted legal way to communicate between a company and a customer. So when you don't year your email that's like not reading your snail mail in the 90s. It might go well for some time, until you miss that one message about a late payment or something...
A large number of services that send various billing etc things via snail mail and email also send text messages. The other part of this is that almost everything is automated these days for most people. Bill payment etc happens automagically. Most necessary notifications occur via phone apps.
replyIgnoring email works just fine, as evidenced by the fact that the majority of people I know don't check email unless it is for their work. Zero impact on their lives. It is the same with snail mail. I think I check my snail mail 6-8 times per year mostly so that the letter box doesn't physically overflow with junk.
