lol no one is getting personal emails, maybe some people get one every few months, but most probably never (not taking into account other than order/shipping confirmations, login codes, etc)
Sports communications at most travel/rec leagues is via group chat / Whatsapp / FB group.
And as a bit of anectata: I play two sports and my child plays multiple. Every single one of those groups or teams relies on email, even when other modes of communication are layered on.
