WhatsApp and email marketing are two powerful tools that businesses can leverage to enhance customer engagement and drive sales. WhatsApp offers a direct and personalized approach, allowing for real-time communication and high engagement rates, making it ideal for customer support and urgent promotions. Email marketing, on the other hand, provides a scalable platform for reaching a wide audience with targeted campaigns, offering detailed analytics for campaign optimization. Both platforms are cost-effective and can be tailored to meet specific business needs.
