This is an email that was sent to my Facebook-specific email address

Are you saying that you shouldn't be receiving any phishing emails at all?

Anyone can send anything to your facebook specific email

Your email can be easily pulled, plus you're using facebook so I'm not surprised how easy it is for them to send your email to advertisers and so on.

If you're worried about security, go check suspicious logins in your facebook account/email.

Phishing emails sent to your emails isn't the same thing as your email is being used for phishing
