The exchange email -> ebook in itself isn't problematic with regards to the GDPR, phrasing it not as an exchange but a free gift is. edit: You may of course not like my comment, but it is factually correct: GDPR really doesn't forbid combining the newsletter entry with a bait like a free ebook, as long as you don't phrase the newsletter membership as "free" and use double opt-in.
