To be fair Facebook used to send an enormous amount of spam emails, at least to me. Years ago when I used it somewhat regularly they used to constantly shuffle their contact preferences and the effect was that I was constantly opted back in to an insane amount of emails. Eventually I just started marking them as spam until Gmail blocked everything they send. I've seen family Email addresses fairly recently full of Facebook junk too so I assume they still default to sending a lot.
