Leveraging email marketing is one of the most effective strategies for how to promote your book on Amazon and reach a highly engaged audience. By building a targeted email list, you can share exclusive updates, launch announcements, and early-bird discounts with readers who already care about your work. Personalized email sequences help strengthen author-reader relationships and encourage subscribers to leave reviews, which boosts visibility on Amazon. You can also segment your audience to send tailored content that resonates with different reader groups. With consistent communication, email marketing becomes a powerful tool to increase sales and long-term Amazon ranking.
