HOA actions seem like exactly the sort of thing I should be receiving by mail. I think this thread is referring to not wanting things like "To {YOUR_NAME} or Current Resident" or spam offers via mail, which are a waste.
Right. I'm sure most of would agree that we don't want to normalize robocall phone calls for anything that isn't really immediate and urgent. And failing that, email isn't necessarily reliable (spam filters/changes/getting lost in all the clutter), which pretty much leaves physical mail. So, yes, even if most people will just throw it in the trash I do want to receive notification of town meetings and other official actions that affect me by mail. I certainly also wouldn't want to normalize posting something on Next Door or Facebook to be a sufficient alternative.
