Yes, WhatsApp boasts an incredible 98% open rate and 45-60% click-through rate, significantly outperforming SMS, which typically sees a 90% open rate and a much lower 6-10% click-through rate.
Can I use rich media in SMS marketing?
Unlike WhatsApp, standard SMS is limited to plain text with a 160-character limit. WhatsApp allows you to send high-quality images, videos, PDFs, and interactive buttons without strict character limits.
