The full text for that section:
All Service Plans may include: (i) promotional content, (ii) sponsorships, and (iii) advertisements before/after playback of Content and in channels, live/as-live, special events, and any third-party services content.
Perhaps you could share, from the email, what you read that everyone else is missing.
