WhatsApp marketing lies in its accessibility and user engagement. Since WhatsApp is already widely used for everyday communication, people are more likely to read and respond to messages sent through the app. Open rates on WhatsApp are significantly higher than email, often exceeding 90%, which makes it an ideal channel for timely and impactful messaging. Moreover, businesses can send not just text, but also images, videos, PDFs, audio messages, and links, making the communication dynamic and engaging. This is particularly useful for sharing product catalogs, promotional offers, event invites, or even personalized recommendations.
