Post the link to "New Q&A activity regarding: AirPods"
This sounds to me like a "search" or some other "digest" of new articles with a "TAG" about AirPods - where you could have chosen to "Follow" these are a mystery to me.
There are "newsletter" (ish) emails that you can choose on your https://appleid.apple.com/account/manage page - but I see no way of "refining" these to AirPods.
The quoted line does not appear in email notifications that I get - mine says, " You are receiving this email from Communities. You can change your email preferences in your Communities Profile. Please expect a slight delay in visibility of points awarded. "
