No, emails that you ask to receive are the definition of solicited email. When was the last time the grocery store emailed you confirming that you'd just paid for your groceries?

Never because my grocery store isn't a website.

OK. When was the last time facebook emailed you to confirm that you liked a comment?

The last time I had Facebook emails before I marked Facebook as spam every action which somehow concerned me on Facebook resulted in me getting a email and consequently flooding my inbox. Admittantly this was a few years ago when I finaly had enough of it so they might of gotten better but at one point they did.

Yes, I picked facebook as an example specifically because of their reputation for emailing you about everything. But I think you'll find that they tend to email you when other people do something that, in some sense, concerns you, not when you do something. (Remember the ancestor comment defining "solicited email" as email that responds to an action you take.) "This person just liked your comment" emails are plausible. "You just liked this person's comment" emails are self-evidently absurd, but they fall perfectly within the (spurious) definition of "solicited" that nitrogen wants us to believe in.

My grocery store gives me a printed receipt when I pay for my groceries. And I don't ask them to do that--they just print one up and hand it to me.

Amazon can't give you a printed receipt because you are not there, physically. So they send you an email instead.

This is not that hard to understand.

Stores don't give you receipts for your benefit. They print receipts to make sure the cashier isn't dipping into the cash register.

Card processors require retailers to provide transaction receipts to cardholders.

Every time I order groceries. Then again my grocery store is online.
