SMSGatewayHub's missed call engagement platform already lets your brand interact with customers through just a missed call. Missed call to WhatsApp takes it further: it taps directly into your customer's WhatsApp inbox, and customers can start communicating with your brand without adding your number to their contact list.
WhatsApp is a free mobile app that uses the smartphone's internet connection to chat with other users without SMS charges, and it is one of the world's leading messaging apps with an approximate 1.5 billion monthly active users. That kind of reach makes the customer's WhatsApp inbox one of the most valuable places for a brand to be.
The service remains low cost and high ROI, while adding a much richer conversation channel on top of your existing missed call campaigns.
