Overview

BookBub is a book discovery and marketing platform that sends a free daily email highlighting free or deeply discounted ebooks, with readers choosing genres to personalize recommendations. Publishers submit deals, and BookBub’s editors select a small share (about 10–20%) based on factors like critical acclaim, price, and reviews; subscribers receive tailored deals by email and can click through to major retailers to purchase, while revenue comes from Featured Deals and BookBub Ads. Unlike many retailers, BookBub does not sell books itself but surfaces deals through curated content and an open advertising marketplace, and it expanded with Chirp to offer discounted audiobooks. Its goal is to help readers find books that match their interests while giving authors and publishers an effective channel to gain exposure and grow sales.
