We approve most media outlets, booksellers, and librarians. However, just having an Instagram does not count as a "media professional" in our eyes, and we will count those submissions as "Consumer Reviewers."
For Consumer Reviewers, please have the social media on which you discuss books, including Goodreads, linked to your profile, and, if you have a website, please include that as well. If your Netgalley review rating is under 40% and you have no social media linked, we will almost never accept your review request (because it appears as if you don't actually review books).
