Is it spam if I put the following message on my broadcast emails?

“THIS MESSAGE IS BEING SENT IN COMPLIANCE OF THE EMAIL BILL: SECTION 301. PER SECTION, PARAGRAPH (a) (2) (c) of S. 1618. To discontinue receipt of further notice and to be removed from our database, please reply with the word Remove in subject.”

Our answer: If you are sending a non-requested, broadcast email
message, it’s spam no matter what you write at the end of it!
In fact, lots of well-known spammers stick that message on their
emails to look more official. However, no boilerplate copy of this
nature, no matter how legal sounding, can save you from accusations of spam and various repercussions.
