TL;DR
WhatsApp offers three distinct products for business communication: WhatsApp Messenger (personal), WhatsApp Business App (small business), and WhatsApp Business API (enterprise). Understanding these differences helps you choose the right solution for your conversational marketing strategy and unlock WhatsApp’s 2+ billion user base.

For businesses, this shift presents a massive opportunity. WhatsApp messages see 98% open rates (compared to 20% for email) and 45-60% click-through rates on promotional messages. The question isn’t whether to use WhatsApp for marketing, but how.
