GDPR article 2(2)c. It will not apply to the receiver of the email, but maybe to the provider. Perhaps it depends on the kind of relationship between the two parties. Mailing lists will be covered. Side note: I know someone who requested their data to their DPA, and part of the response contained emails mentioning them and their complaints in the _content_ of the message (they were not in the From:, To:, Cc:, or Cci: fields). All names and emails address were censored, though, in accordance with 15(4).
