What is WhatsApp marketing? WhatsApp marketing is directly interacting with consumers or potential customers on the WhatsApp platform to promote goods, services, or brands. This is highway marketing; forget the detours. Consider delivering communications directly to a person's chat inbox—the area they are most likely to visit. You're there, in between conversations with Mom and weekend plans with pals; you're not simply another unread email or a pop-up ad that can be quickly ignored. The allure of WhatsApp marketing lies in that.
