A clothing brand launches a WhatsApp campaign for its end-of-season sale. The message is opened almost immediately. A few customers purchase right away. The campaign is over, and the team moves on. What happened to the customers who opened the message and planned to come back later? Most never received a WhatsApp follow-up message. That is where many businesses leave revenue on the table. WhatsApp messages have an open rate of 98% , but visibility alone does not drive conversions.
