Email notifications for chat should respect "private email" site setting

If it did cover chat, would that be your preferred approach to meet the need within your community? Or would you prefer emails from chat to be disabled entirely still?

Yes, our preference would be for chat notifications to still go out but just be stripped of all content like the ‘private email’ feature does.

Should “not” be “now” above?

Yes, thanks for noticing that.
